The strong high pressure is still over the western U.S.   Today and Thursday we will be sunny with temperatures about like yesterday or a little hotter.   There will continue to be afternoon and evening thunderstorms along the Sierra Crest south of Lake Tahoe.    Friday the high will begin to slowly weaken and next week we will be under a weather pattern like the one shown on the map below.  Not a big change from the current pattern but temperatures will cool back to normal or a few degrees above.  Skies will continue sunny...except for a chance of afternoon and evening thunderstorms, Friday through Sunday, over Modoc, eastern Lassen, and eastern Plumas counties.  Winds will be light.

Normal high and low temperatures for June 27-July 4 (high/low)...Redding 97/65, Chico 95/60, Quincy 87/43, Chester 82/44, Susanville 86/49, Grass Valley 85/55, Weaverville 90/47, Mt. Shasta 82/49, Yreka 87/50, Alturas 84/43

This blog will be issued every Monday morning and updated if the weather is changing or critical or interesting weather events are occurring.

The satellite picture and forecast map below show high pressure continuing over the western U.S.   This means mostly clear skies for the inland areas of Northern California for the next 7 to 10 days.  Temperatures today through Thursday will be running 8 to 12 degrees above normal.  Wednesday looks like the warmest day when some areas of the north valley will be 106 to 109.  Winds will be light.

The high will weaken slightly Friday through the weekend.  We will still continue to have mostly sunny skies but temperatures will cool to near normal by the weekend.

Weather Discussion for Saturday June 25, 2016

Normal high and low temperatures for June 20-June 27 (high/low)...Redding 94/63, Chico 93/58, Quincy 84/43, Chester 81/42, Susanville 83/47, Grass Valley 83/53, Weaverville 88/46, Mt. Shasta 80/47, Yreka 85/48, Alturas 81/42

This blog will be issued every Monday morning and updated if the weather is changing or critical or interesting weather events are occurring.

Here comes the heat....The high pressure area that has been over the western and southwestern U.S. is finally beginning to push northward.   A large high pressure ridge will dominate our weather for the next 7 to 10 days. (see map below).   Expect mostly clear skies with temperatures rising to above normal today and then continuing to rise through midweek.   Temperatures by Wednesday will be 12 to 18 degrees above normal with some areas in the north valley bumping the 110 degree mark.  A combination of the high weakening slightly and marine air flowing through the Delta into the valley will bring slightly cooler temperatures Thursday and Friday.

Gusty north winds will occur in some areas today with light winds the rest of the week.

Normal high and low temperatures for June 20-June 27 (high/low)...Redding 94/63, Chico 93/58, Quincy 84/43, Chester 81/42, Susanville 83/47, Grass Valley 83/53, Weaverville 88/46, Mt. Shasta 80/47, Yreka 85/48, Alturas 81/42

This blog will be issued every Monday morning and updated if the weather is changing or critical or interesting weather events are occurring.

High pressure is still over the west.   However,  low pressure troughs and frontal systems moving by to our north are keeping it's orientation west to east.   This means it can't ridge or push northward which would bring much hotter weather to the north end of the state.  Today we will see sunny skies with temperatures about like yesterday, winds will be light.  Thursday a low pressure trough will move through western Canada and the Pacific Northwest.  This system will bring a few clouds to the areas north of Redding.  There could be a few light sprinkles over the northwest corner of the state.  Temperatures will cool a few degrees and south to southwest winds will increase in the afternoon.   Friday will be sunny with gusty north winds and temperatures near normal.

Saturday through next week the high pressure ridge will continue over the western U.S.  (see map below).   It looks like the flow across western Canada will weaken slightly and this will allow the high to push northward.  This means look for hotter weather next week.

Weather Discussion for Monday June 20, 2016

Normal high and low temperatures for June 20-June 27 (high/low)...Redding 94/63, Chico 93/58, Quincy 84/43, Chester 81/42, Susanville 83/47, Grass Valley 83/53, Weaverville 88/46, Mt. Shasta 80/47, Yreka 85/48, Alturas 81/42

High pressure is over the western U.S. and will hold there for the next week (see map below).  The high is oriented in an east to west direction and this will keep the hotter air to our south.   Not a lot to blog about today.   Sunny with temperatures 5 to 10 degrees above normal for the nest week.   This should be the north valley in the upper 90s to 104.  Winds will be light.

Last week's low pressure trough brought over 2 inches of rain to the Redding airport over a 3 day period, with heavier amounts in the outlying areas.

Earlier this week it looked like the low pressure area would drop southward along the coast and then move northeastward Friday.   Well the low is moving a little slower than expected and is still along the coast and won't lift northeastward until tomorrow.   Partly cloudy to cloudy today through midday Saturday with scattered showers and thunderstorms and below normal temperatures,  The showers will end in most areas by midday Saturday but will continue until Saturday evening over Modoc, Lassen, and Plumas counties.  Temperatures Saturday will be a little warmer but still below normal.

Sunday through the mid part of next week a strong high pressure area will be over the western U.S. with a weak low pressure area to our west.   During this time will see sunny skies with some afternoon cumulus clouds over the mountains.(see map below).   There could be afternoon thunderstorms along the Sierra Crest Wednesday.  Temperatures Sunday will be back to normal and then above normal Monday through Wednesday....some north valley areas will break the 100 degree mark.

Thursday the high pressure area will weaken as the off shore low pressure area pushes closer to coast.   Thursday through the weekend we will still be mostly sunny but there will be an increase in afternoon and evening thunderstorms over the mountains.   Temperatures will be a few degrees above normal.

A cold...for this time of year... low pressure area is deepening off the coast.   This system will be just off the Northern California Coast Thursday and then lift northeastward Friday.   Today the north state will be partly cloudy to cloudy with scattered light showers.  The precipitation will increase tonight and Thursday we will see periods of rain or showers with thunderstorms possible.  Some of the higher elevations could see between .50 and 1 inch of rain.   Temperatures will be well below normal and snow levels will drop to 5500 to 6000 feet.   Gusty southwest to northwest winds will occur today and Thursday.   Friday the low will lift northeastward as high pressure begins to rebuild over the western U.S.  There will still be some showers on Friday but they will be over the higher elevations and will be decreasing during the day.  

The weekend will be sunny as the high pressure area continues to build.  Temperatures will be normal or a few degrees above by Sunday and gusty north winds will occur late Saturday and early Sunday.  

Monday and all of next week a very strong high pressure area will be over the western U.S. (see map below).  We will see sunny skies with temperatures 8 to 12 degrees above normal...which means the north valley will be over 100 degrees...
