Weather Discussion for Friday August 1, 2014


Normal high and low temperatures for this week July 28-Aug 3 (high/low)...Redding/Red Bluff 100/66, Chico 97/60, Quincy 91/44, Chester 87/46, Susanville 90/51, Grass Valley 89/57, Weaverville 96/49, Mt. Shasta 87/51, Yreka 94/54,  Alturas 91/45. 
-------------------------------------------------------------------------

High pressure will continue just to our east for the next week.   Temperatures will continue above normal...although they will cool slightly this weekend especially in the valley south of Marysville where marine air will provide a little more cooling.

The other feature we will continue to deal with is sub tropical moisture coming northward and afternoon and evening thunderstorms.   The winds aloft and now southwesterly and will remain that way through early Sunday.  This pushes the thunderstorm activity eastward.  Today through Sunday the threat of thunderstorms will be over eastern Siskiyou, Modoc and Lassen counties and along the Nevada border.  There continues to be some indications in some of the longer range forecast models of a weak upper level low pressure area forming off the coast (see map below) early next week.  If this happens then the threat of thunderstorms will be spread back over all of the higher elevations of the north state.   Light to moderate southwest winds are expected in the afternoons through Sunday.

There are several large fires burning in the north state so we will begin to see an increase in reduced visibility due to smoke.

Weather Discussion for Thursday July 31, 2014


Normal high and low temperatures for this week July 28-Aug 3 (high/low)...Redding/Red Bluff 100/66, Chico 97/60, Quincy 91/44, Chester 87/46, Susanville 90/51, Grass Valley 89/57, Weaverville 96/49, Mt. Shasta 87/51, Yreka 94/54,  Alturas 91/45. 
-------------------------------------------------------------------------

Ref the question yesterday....Latest forecast is for a weak to moderate El Nino, which is pretty much a coin flip on whether we have a a wet or dry winter.   My concern or fear is that this summer is similar to 1976 which followed a very dry winter and was also a weak to moderate El Nino year.  The winter of 1977 was dry and the next summer Shasta Lake hit its all time low.  Hopefully the El Nino will strengthen which would give us a higher probability of a wet winter.

We continue...for the next week... to have a high pressure ridge to our east with sub tropical moisture being pulled northward.   The upper level winds are shifting to the southwest which will begin to push the afternoon and evening thunderstorm threat eastward.   Today there will be thunderstorms over Siskiyou, Modoc, Lassen, eastern Plumas and eastern Nevada counties.  Friday through the weekend the thunderstorm threat will be Siskiyou, Modoc, and Lassen counties.   Early next week the flow aloft will shift back to the south and this will spread the thunderstorm activity back over the coastal and northern mountains.   Areas not affected by the thunderstorms will be mostly sunny.

Temperatures will continue 4 to 8 degrees above normal with a couple of degrees of cooling this weekend.

Weather Discussion for Wednesday July 30, 2014


Normal high and low temperatures for this week July 28-Aug 3 (high/low)...Redding/Red Bluff 100/66, Chico 97/60, Quincy 91/44, Chester 87/46, Susanville 90/51, Grass Valley 89/57, Weaverville 96/49, Mt. Shasta 87/51, Yreka 94/54,  Alturas 91/45. 
-------------------------------------------------------------------------

Only subtle changes in the large scale weather pattern over the next week.  The large high pressure area is to our east with subtropical moisture flowing northward over California.   Today will be a repeat of yesterday with temperatures about like yesterday and afternoon and evening thunderstorms over Trinity, Siskiyou, northern and eastern Shasta, Modoc, Lassen, Plumas, and eastern Nevada counties.  Thursday through Sunday the afternoon and evening thunderstorm threat will be over Siskiyou, Modoc, Lassen, and northern and eastern Plumas counties.  Temperatures will be slightly cooler than today but still above normal.

Late in the weekend and early next week a weak upper level low pressure trough will try and form off the coast (see map below).  If this develops like shown below the thunderstorms would be pulled back into the coastal mountains.   Temperatures will remain above normal.

As you can tell from the forecasts.   These summertime sub tropical moisture patterns are hard to forecast.  If the winds aloft are southerly or southeasterly the thunderstorms will be widespread over the higher elevations.  If the winds shift 20 degrees to the southwest the thunderstorm threat will be along and east of the Sierra Cascade Crest.

Normal high and low temperatures for this week July 28-Aug 3 (high/low)...Redding/Red Bluff 100/66, Chico 97/60, Quincy 91/44, Chester 87/46, Susanville 90/51, Grass Valley 89/57, Weaverville 96/49, Mt. Shasta 87/51, Yreka 94/54,  Alturas 91/45. 
-------------------------------------------------------------------------

The large high pressure area is just to out east will stay there for the next week.

Another surge of sub tropical moisture is now over Northern California with partly cloudy skies over the areas east of the valley.  The high pressure area is still to our east and will continue to pull moisture northward.   Today and Wednesday we will have afternoon and evening thunderstorms over Trinity, Siskiyou, Modoc, Lassen, Plumas, and eastern Nevada counties.  The rest of the north state will be sunny with some afternoon clouds.  Temperatures today and Wednesday will be about like yesterday.

Thursday and Friday the flow aloft will become more southwesterly and the afternoon and evening thunderstorm threat will shift a little eastward...eastern Siskiyou, Modoc, Lassen, Plumas, and eastern Nevada.   The rest of the north state will be mostly sunny with afternoon clouds.    Temperatures will continue above normal.

The weekend and early next week the high will still be to our east but there will be a weak upper level low pressure area form along the coast.   (see map below).  This will pull the moisture back to the west and bring a threat of thunderstorm to Mendocino, Trinity, Siskiyou, higher elevations of Shasta, Modoc, Lassen, Plumas and Nevada counties.  Temperatures will cool to normal or slightly above.

Normal high and low temperatures for this week July 28-Aug 3 (high/low)...Redding/Red Bluff 100/66, Chico 97/60, Quincy 91/44, Chester 87/46, Susanville 90/51, Grass Valley 89/57, Weaverville 96/49, Mt. Shasta 87/51, Yreka 94/54,  Alturas 91/45. 
-------------------------------------------------------------------------

The high pressure ridge is still just to our east and as the map below shows won't be going anywhere for a while. ...if you read the comment from Cheyenne in yesterday's blog you can see that on the other side of this ridge things are really different.     The high pressure area will keep temperatures above normal.  However, the fly in the ointment is the surges of sub tropical moisture that are begin pulled northward.   This morning's satellite picture below shows quite a bit of cloudiness over Southern California moving northward.  

Today we will see mostly sunny skies with clouds increasing from the south during the afternoon.  There is a chance of isolated thunderstorms this afternoon along the Sierra Crest from Plumas county southward.  Temperatures will be about like yesterday's, except in the valley from Chico southward where marine air from the Delta will cool things down.  

Tuesday through Thursday we will see more cloudiness due to the moisture from the south.   The north state will be partly cloudy to partly sunny with a chance of thunderstorms over Siskiyou, Modoc, Lassen, Plumas, and eastern Nevada counties.  The clouds will cool the temperatures slightly but they still should be above normal.

Friday through the weekend we will see mostly sunny skies with a chance of thunderstorms along and east of the Sierra Cascade Crest.

Weather Discussion for Sunday July 27, 2014


Normal high and low temperatures for this week July 21-July 27 (high/low)...Redding/Red Bluff 100/66, Chico 97/61, Quincy 91/45, Chester 88/47, Susanville 90/52, Grass Valley 89/57, Weaverville 96/50, Mt. Shasta 88/51, Yreka 93/54,  Alturas 91/46. 
-------------------------------------------------------------------------

A strong high pressure area is just to our east and will  hold there for at least the next 5 to 7 days. (see satellite picture and map below)  The forecast problem will be the timing of the surges of sub tropical moisture that are being pulled northward by the southerly flow around the west side of the high.  Yesterday it looked like the clouds off the southern California coast would move northeastward and be over the Sierra Cascade area by this afternoon.   Instead during the night the clouds moved straight northward and expanded.   Today the north state will be partly cloudy with the chance of isolated showers and thunderstorms over the higher elevations.  Monday through Wednesday more sub tropical moisture will be pulled northward and this will bring an increased threat of afternoon and evening showers and thunderstorms over the foothills and mountains.  Thursday through Saturday the flow aloft will become southwest and this will push the moisture a little eastward and the thunderstorm threat will be in eastern Siskiyou, Modoc, Lassen, Plumas and eastern Nevada counties.

The amount of cloud cover you area has will influence the temperatures.  Partly sunny to sunny areas will be 4 to 8 degrees above normal while partly cloudy areas will be close to normal.   Winds will be light except gusty near the thunderstorms.

Well here we are back in our summertime heat pattern.    The strong high pressure area is just to our east and will hold there through the next week. (see map below).   Temperatures will be 5 to 10 degrees above normal for the next week and winds will be light.   The southerly flow around the west side of the high pressure area will begin to pull sub tropical moisture northward.  We will begin to see this moisture reach the Plumas and Tahoe area by Sunday.   Monday through Friday the north state will have a chance of isolated afternoon and evening thunderstorms over the higher elevations.
