February 16th, 2012 Forecast

 A weak (not as weak as yesterday) storm system will move through the region tomorrow afternoon, spreading light rain through the area from midday on.  While for the vast majority of the region this looks like a rain only event, the Poconos and perhaps the higher hills of the Lehigh Valley may have some light snow on the very front end of the storm system, which may coat the ground briefly before milder air nudges them over to rain.   Rainfall amounts with this system do not look terribly impressive, generally on the order of a quarter of an inch or less as it moves through.

Until we get there, tonight features a mix of clouds and stars...clouds don't increase in percentage until after Midnight.  Low temperatures drop into the upper 20's and lower 30's outside of the city, around 35 in Philadelphia.   Highs on Wednesday generally range from the lower 40's northwest to the lower 50's south of the city, with Philly projected to get to 48.   Light rains should move in after midday tomorrow.

Modeling continues to hint, although inconsistently, of a storm system on Sunday that could bring rain and/or snow to the region.  Last night's run of the GFS hinted at the storm coming up the coast (as rain for the Philly metro, south and east) while the European computer model flipped from showing a storm to missing the storm altogether.  Other supplemental guidance like the Canadian computer model are showing a miss as well in this morning's runs.  We will keep an eye on it!
