WEEKEND WEATHER OUTLOOK

High pressure centered over the mid Atlantic region drifting eastward will keep us dry over the weekend.  A very wet  low pressure system  near Florida is expected to be suppressed to our south by this high.

Saturday: A return southerly flow of moisture in the upper levels of the atmosphere will bring some cloudiness to our area on Saturday.  The cloudiness will be of the high level variety (20,000 ft) and there may be some sunshine through the cloudiness.   Temperatures slowly moderate to near 40.

Sunday: The upper air moisture and vorticity will have moved past us.  Sunny skies are expected.

The models have been insistent that the Florida low pressure will not come up the coast, although some recent  model runs have some cloudiness as far north as Delaware late Sunday. High near 50!

 

FORECAST UPDATE 9 AM

My snow forecast last night of “a coating at best” needs to be revised downward to virtually nothing.

Temps remain even warmer than predicted (34 º+)  and available moisture is very low right now.   QPF was only predicted at 0.01 inches water per hour and that’s turning out to be model noise.

Current radar is unimpressive:

So with predicted precipitation so small, most of the models showed model noise as precip.   (Looking back, the Canadian high resolution model from last night got this right.)  Heavier rain is expected tonight.
