KEY MESSAGES
* EXPECT WIDESPREAD FREEZING TO NEAR FREEZING TEMPERATURES ON
TUESDAY MORNING.
* A RIDGE BUILDS BACK INTO THE REGION BY MID-WEEK, ALLOWING FOR
WARMER AND DRIER CONDITIONS INTO THE WEEKEND.
DISCUSSION
* TODAY IS ON THE CHILLY SIDE ACROSS THE REGION WITH BELOW AVERAGE
TEMPERATURES AND BRISK NORTH-NORTHEAST WINDS. LOW TEMPERATURES
TONIGHT WILL FALL BETWEEN 30-40 DEGREES IN WESTERN NV, AND 20-30
DEGREES FOR THE EASTERN SIERRA COMMUNITIES. THESE READINGS ARE A
FEW DEGREES WARMER COMPARED TO MONDAY MORNING, BUT STILL AROUND
5-10 DEGREES BELOW AVERAGE. WINDS WILL REMAIN EAST TO NORTHEAST
INTO THE TUESDAY, BUT WILL SUBSIDE IN STRENGTH BY TONIGHT.
* A GRADUAL WARMING TREND WILL RESUME ON TUESDAY AND CONTINUE INTO
THE WEEKEND. HIGH PRESSURE IN THE EAST PACIFIC WILL SLOWLY
EXPAND EAST OVER THE REGION, WHICH WILL INCREASE ATMOSPHERIC
THICKNESSES AND 500MB HEIGHTS. THIS WILL ALLOW FOR TEMPERATURES
TO TREND UP INTO THE LOW TO MID-80S IN WESTERN NV AND EASTERN
LASSEN COUNTY, AND THE MID TO UPPER 70S FOR THE EASTERN SIERRA
COMMUNITIES. THIS WILL BE ACCOMPANIED BY MUCH LIGHTER WINDS,
AND DRY WEATHER.
* FOR THE UPCOMING MEMORIAL DAY WEEKEND, THE ENSEMBLES SHOW
ANYTHING FROM RIDGING WITH DRY CONDITIONS AND ABOVE AVERAGE
TEMPERATURES, TO A TROUGH PATTERN THAT IS WETTER AND COOLER. SO,
KEEP INFORMED OF THE CHANGES TO THE FORECAST THIS WEEK AS WE
APPROACH THE HOLIDAY WEEKEND. -MCKELLAR
