A COMPLEX WEATHER SYSTEM MARCH 3-5

2015-03-03 19:37:22 emccmp

Weather briefing WFO PHI – 2015-03-03 500 PMTwo weather systems will be affecting our area over the next several days. A briefing package is attached,
with the Executive Summary as follows:

Synopsis: A warm front will lift north through the area tonight. A cold front will then cross the area from west to east on Wednesday. This front will sag to our south into Thursday as an area of low pressure develops along it. This will all result in a complex and prolonged period of precipitation from Tuesday afternoon into Thursday.

Precipitation which begins as snow today will change over to sleet and freezing rain from south to north as warmer air moves in. This changeover from snow to sleet to freezing rain, then rain will occur by this evening south of the C&D canal, reaching the I-95 corridor later this evening before moving further north overnight. An inch or two of snow/sleet accumulation is expected north and west of Philadelphia before the changeover to rain is complete in the far north during the late overnight hours. Winter Weather Advisories have been posted. Please see following snowfall and icing maps.

As colder air filters back into the region Wednesday night, precipitation will change back over to snow from north to south. Four to eight inches of snow is possible from this system. Winter Storm Watches have been issued. Please see snowfall total maps on following slides. The Wednesday evening and especially the Thursday morning commute will be affected.

Colder temperatures will linger into Friday, but then moderation is expected for the weekend…still below normal for this time of year, but better than what we’ve had lately.
