Weather Discussion for Saturday December 20, 2014


Normal high and low temperatures for this week Dec 17-Dec 23 (high/low)...Redding/Red Bluff 55/35, Chico 54/35, Quincy 45/24, Chester 41/19, Susanville 40/21, Grass Valley 52/31, Weaverville 47/29, Mt. Shasta 43/25, Yreka 44/25, Alturas 42/17. 
-------------------------------------------------------------------------
 Blog might be a little late this morning.   I opened the paper and the headline was that NOAA had changed the 90 day forecast to wet for Northern California.  So I went to their site and read their discussion that went with the forecast map.   They really haven't changed their large scale forecast.   The discussion still says 60% chance of a weak to moderate El Nino.  The map still has dry conditions over Washington and part of western Canada, which would reflect the position of the high pressure area.  They have expanded the above normal precipitation area northward to reflect the stronger jetstream we have over the past month.   One thing I have noticed over the years is that these forecasts sometimes seem to reflect the weather you are currently having.   Let's hope they are right.
**********************************************************************

This morning's satellite picture (below) shows high pressure building just off the coast with a low pressure area and frontal system moving into the Pacific Northwest.   This system has a lot of moisture and clouds associated with it and these clouds are spilling over the ridge and into Northern California.  Today the north state will be cloudy with light to moderate rain along the coast and over Mendocino,  Trinity, Siskiyou, Shasta, and Modoc counties and light rain or showers elsewhere.   Snow levels will be 6000 feet or higher and gusty south winds will occur in some areas.  Sunday the high will have pushed further northward and this will also push the clouds further northward...by Sunday afternoon there will still be some clouds north of Redding but the areas south will be partly to mostly sunny.

Monday and Tuesday a strong high pressure ridge will be along the coast.   The north state will be mostly sunny with night and morning valley fog.  Temperatures will be 5 to 10 degrees above normal in the areas above the fog.   In the Sacramento Valley most of the fog will be south of Red Bluff.

Wednesday the high pressure weakens as a low pressure trough drops  southeastward across Northern California.  (see map below).  This system will not have a lot of moisture with it but will bring clouds to the area with showers mainly over the areas north and east of the valley.   Colder air will drop into our area as this system moves through.

Thursday and Friday we will see sunny skies with gusty north winds winds in some areas.

Weather Discussion for Friday December 19, 2014


Normal high and low temperatures for this week Dec 17-Dec 23 (high/low)...Redding/Red Bluff 55/35, Chico 54/35, Quincy 45/24, Chester 41/19, Susanville 40/21, Grass Valley 52/31, Weaverville 47/29, Mt. Shasta 43/25, Yreka 44/25, Alturas 42/17. 
-------------------------------------------------------------------------

Well the valley didn't get the break  in the clouds yesterday afternoon, that I thought we would see.  The off shore system moved a little faster than expected and this kept the fog and drizzle packed in the valley.  The frontal system is now moving across Northern California.  This system is bringing rain to all of the area with snow levels around 5000 feet.   The precipitation will turn to showers later today and tonight.

Saturday high pressure will be starting to build along the west coast.   However, the storm system...low pressure areas....you see out in the Pacific on this morning's satellite picture (below) will be moving into the Pacific Northwest.  This system has a lot of moisture associated with it so even though the high pressure ridge will be building, the north state will be cloudy Saturday with rain on the coast and over Mendocino, Trinity, Siskiyou, northern Shasta, and Modoc counties with scattered light showers elsewhere.   The snow level will be 6000 feet.   Gusty south winds will occur Saturday.

Sunday the clouds will breakup and get pushed northward as the high pressure ridge continues to build along the coast and by midday the areas north of Redding will be partly cloudy with partly sunny skies south of Redding.

Monday and Tuesday the high pressure ridge will dominate out weather.   Skies will be sunny except for night and morning valley fog.  Daytime temperatures will be 5 to 10 degrees above normal in the areas above the fog.  Winds will be light.

Late Tuesday the high pressure ridge will begin to weaken as a low pressure trough moves across the Gulf of Alaska.  (see map below).  This system will bring clouds and colder air to the north state Wednesday with scattered showers mainly over the higher elevations.  Snow levels will be 4000 feet.  Skies will be clearing late Wednesday.  Thursday will be sunny and cool with north winds.

Weather Discussion for Thursday December 18, 2014


Normal high and low temperatures for this week Dec 17-Dec 23 (high/low)...Redding/Red Bluff 55/35, Chico 54/35, Quincy 45/24, Chester 41/19, Susanville 40/21, Grass Valley 52/31, Weaverville 47/29, Mt. Shasta 43/25, Yreka 44/25, Alturas 42/17. 
-------------------------------------------------------------------------

Ref the question yesterday...The Farmers Almanac...The Old Farmers Almanac...NOAA/NWS....
I can see where one of the Almanacs probably looks more accurate.  However, the NOAA forecast was the type of weather pattern you would see from an El Nino pattern which is what the large scale weather pattern has been. Notice the high pressure area over northern Canada or eastern Alaska on this morning's satellite picture  and the forecast map below.  This is the signature of an El Nino or warmer ocean pattern.   Like I have said before with a weak or moderate El Nino there is no strong correlation to a wet or dry weather pattern for Northern California.  If this high stays close to our area we stay dry if it moves northward into Alaska we will be wet if the southern branch of the jetstream is strong.  Probably not a good answer but I think longer range weather forecasts are probably more useful when in a statistical format or large scale weather pattern maps.
*****************************************************
Yesterday's storm is moving a little slower than expected.   There will still be a few light showers this morning and early afternoon over the higher elevations.  The clouds will be decreasing during the day and the fog that blankets the valley will be breaking up...by this afternoon we will see partly cloudy skies to partly sunny skies.

The next storm system will reach the coast this evening with rain across Northern California tonight and Friday.  Snow levels will be 4000 to 5000 feet. The precipitation will taper off Friday night.  

Saturday high pressure will be starting to build along the west coast.   However, the low pressure area shown on the far western edge of this morning's satellite picture will be moving over the high and into the Pacific Northwest.  This storm has a lot of moisture with it and the southern end will bring partly cloudy to cloudy skies to the north state Saturday with rain along the coast and over Mendocino, Trinity, Siskiyou, northern Shasta and Modoc counties with a few light showers elsewhere.  Snow levels will be 5000 to 6000 feet.

The high continues to build along the coast Sunday and this will push the clouds northward.  The areas north of Redding will still be partly cloudy but the rest of the area will be partly to mostly sunny and warmer.

Monday and Tuesday the north state will be partly to mostly sunny...except for night and morning valley fog. Daytime temperatures....above the fog...will be above normal.   Winds will be light.

Wednesday the high pressure ridge will pull back to the west and this will allow cold but relatively dry low pressure area to drop southward into to Nevada.  This system could bring a few snow flurries along and east of the Sierra Cascade Crest, with colder air moving into all of Northern California.

*****************************************************************

Weather Discussion for Wednesday December 17, 2014


Normal high and low temperatures for this week Dec 17-Dec 23 (high/low)...Redding/Red Bluff 55/35, Chico 54/35, Quincy 45/24, Chester 41/19, Susanville 40/21, Grass Valley 52/31, Weaverville 47/29, Mt. Shasta 43/25, Yreka 44/25, Alturas 42/17. 
-------------------------------------------------------------------------

Ref the questions yesterday....There really isn't a pressure value that determines whether you in a low or high pressure area.   When you see a weather map it is like a topographic map.   If your pressure is 1000 millibars and the area around you has a pressure of 1020 millibars then you are in a low pressure area.  It is like looking at topographic map.   Redding has an elevation of 500 feet and is in a valley.   Burney is approx 3200 feet but it is also in a valley because the areas around it are higher.   I hope this helps answer your question.   For the question about how long the high pressure area will last see the last paragraph of the discussion below.
***********************************************************

More rain today as another low pressure area is off the coast and moving eastward.   Snow levels will be near 4000 feet.  The rain will turn to showers tonight as the low moves eastward.    Thursday the north state will be partly cloudy to cloudy with isolated showers on the north coast and northwest corner of the state.

Late Thursday and Friday another frontal system will move across Northern California with light to moderate precipitation.   The rain will reach the coast Thursday evening and will spread across the north state Friday morning.  Snow levels with this system will be 4000  to 5000 feet.  The front will be preceded by gusty southerly winds.  The precipitation from this system will be ending Friday night.

Saturday high pressure will be starting to build along the west coast.  However, there will be a storm system moving over it and into the Pacific Northwest.  The southern end of this system will bring clouds to the north state with light rain or showers on the north coast and over Trinity, Siskiyou, northern Shasta and Modoc counties.  There could a few light showers or sprinkles over the north end of the valley and Lassen county Saturday morning and early afternoon.

Sunday a strong high pressure ridge will be along the west coast and will hold there through at least the mid part or next week. (see map below).  During this time we will see mostly sunny skies with night and morning valley fog.  Daytime temperatures will be above normal in those areas above the fog.  Winds will be light.

It looks like the high pressure ridge will persist for 7 to 14 days but it's strength will wax and wane.  This means if the ridge backs a little to the west we will get a shot of cold air from the north and maybe a few showers.  If the ridge weakens a storm could move over the top of it and brush the north state with light rain.  Bottom line while we may see few weak systems the last half of December we probably won't have any more really wet storms.  The longer range climat models don't show a permanent ridge through February.

Weather Discussion for Tuesday December 16, 2014


Normal high and low temperatures for this week Dec 17-Dec 23 (high/low)...Redding/Red Bluff 55/35, Chico 54/35, Quincy 45/24, Chester 41/19, Susanville 40/21, Grass Valley 52/31, Weaverville 47/29, Mt. Shasta 43/25, Yreka 44/25, Alturas 42/17. 
-------------------------------------------------------------------------

Ref the comment yesterday reporting the rainfall north of Redding.   Shasta Lake has risen over 32 feet in 10 days.

A low pressure trough that is still to our west continues to generate storms or frontal systems and push them through Northern California. The next storm system is about to move onshore (see satellite picture below).  Today and Wednesday we will see more rain and showers with snow levels 3500 to 4000 feet.  Gusty south winds are expected this afternoon.  Thursday the low will shift to our east and the north state will have partly cloudy to partly sunny skies.

Friday a weak low pressure trough will move into Northern California with light rain with the snow level 4500 to 5000 feet.   Saturday this system will be moving east of our area but there will be lingering clouds and showers along the coast coast and over Trinity and Siskiyou counties.   The rest of the north state will be partly cloudy to partly sunny.

Sunday high pressure will be along the west coast (see map below) and should hold there for several days.  This will bring partly to mostly sunny skies to the north state, except for night and morning fog in the valleys.  Day time temperatures will be above normal.

Weather Discussion for Monday December 15, 2014


Normal high and low temperatures for this week Dec 17-Dec 23 (high/low)...Redding/Red Bluff 55/35, Chico 54/35, Quincy 45/24, Chester 41/19, Susanville 40/21, Grass Valley 52/31, Weaverville 47/29, Mt. Shasta 43/25, Yreka 44/25, Alturas 42/17. 
-------------------------------------------------------------------------

A large scale low pressure trough extends from the Gulf of Alaska along the west coast.   This system will generate impulses or frontal systems and send them across Northern California through Wednesday.  The first system is moving through  the area today with another expected Tuesday and then another on Wednesday.  Today through Wednesday the north state will have light to moderate precipitation as the systems move through with showers between systems.   Snow levels will be 3500 to 4000 feet north and 4000 to 4500 feet to the south in the Tahoe area.  Gusty south winds will precede each system.

Thursday the north state will be partly cloudy and then on Friday a weak low pressure trough will brush the north state (see map below).  This system will bring light rain to our area Friday and early Saturday.  Snow levels will be 4000 to 4500 feet.  The rain will end Saturday afternoon and Sunday skies will be clearing as high pressure builds along the west coast.

It now looks like the high pressure area could bring a period of dry weather next week.
