Chilly Today then Warmer by the Weekend…..Stormy 2nd half of next week….
Monday April 2, 2012
Posted at 8:50 am by Howard
Today will be the coldest day with highs in the low 30s. Large scale upper trof coming east throughout the far west today. Snow-showers a good bet but little in the way of anything measurable expected.
Tomorrow Friday expect temps up about 5 to 8 degrees over todays….
Then rapid warming expected Saturday to Easter Sunday with highs for the Easter Bunny in the 50s.
So ridging in the upper levels is expected over the weekend then another trof will skirt the area Tuesday for a possibility of some snow showers. The Dweebs are still expecting a larger more substantial trof to bring stormy weather with snowfall of a foot or better next Thursday/Friday…..A full week away.
Forecast from last weekend:
Not only is it spring by the calendar….But spring has arrived in the models too! Lots of smaller scale features instead of the larger scale features found in December through february. The tempo is slower, with not nearly as much cold air as just a month ago……
Both 6 to 10 day and 8 to 14 day outlooks show normal to slightly above normal precipitation for Mammoth through mid month. Although La Nina is all but officially dead, the distribution of precipitation forecasted along the west coast is still La Nina like. Keeping in mind that the PDO is still negative.
The weather this week will feature two Trofs. Neither will be wet for the central sierra other then a few snow-showers Wednesday and Thursday.
The rapidly warming temps between systems highlights springtime in the Sierra. Periods of warm air and cool air advection this week will make up for the most part, this weeks weather.
For Monday and Tuesday, expect highs in the upper 40s then upper 50s Tuesday. Lows at night will be in the 20s.
Winds will highlight the weather again by Tuesday night into Wednesday morning……
