Time and Day: 0630 Friday
The Snapshot:
Light passing showers with rising temperatures
today; rain switching to snow with wind tonight.
Warm
and dry weather begins on Sunday.
The Science: A weak warm
front will push through the region today followed by a strong cold front
tonight. Freezing levels will peak near
5000’ this afternoon and then quickly fall in the wake of the cold front. The main moisture event is associated with the leading edge of the cold
front, so the rain, if any, will be short-lived. Snow intensifies with westerly flow (convergence) late tonight into early tomorrow
morning. The moisture will dissipate tomorrow afternoon
as high pressure build up from the south.
The Long Range: A very warm, dry and stable air
mass will begin to lift north along the west coast on Sunday. Clear
weather with daytime temperatures
possibly reaching into the 50’s can be expected on Monday and Tuesday of next
week.
