Sloppy Mess To Our North

Update, 7 AM: As this first batch of precipitation pulls away over the next couple of hours we'll see intermittent drizzle/light showers, with snow farther north. More rain is farther west in Indiana and that will arrive here later this afternoon into the evening hours.

Radar this morning is showing the family of precipitation types across the region this morning, with rain around Philadelphia, a mix of snow/rain across the northern burbs (especially in Bucks County), and accumulating snow from Quakertown on north.   Around the city proper, we haven't see any snow or sleet mix in but with a steadier and heavier batch of precipitation across Central Pennsylvania on the march it's not out of the realm of possibility that some snowflakes or sleet pellets mix in the city as that batch of precipitation moves in over the next couple of hours.  The morning rush will be "fun" -- similar in some respects to Monday's around here.

As we progress through the daylight hours later today we could see some of the snow to our north mix or change to rain from time to time, especially in periods of lighter precipitation as the atmosphere is not cooling dynamically from precipitation pulling down cool air from aloft and combined with a push of milder air aloft that will reach into the Lehigh Valley later on.   However, a good chunk of the precipitation in the Poconos will fall in the form of snow.   Potentially more than six inches could accumulate in the higher elevations of the Poconos before things are all wrapped up late tonight.  Tobyhanna is up to 4" as of 4 AM this morning.

It's going to be a miserable day no matter how you slice it.    In Philadelphia proper, rain will be off and on, with the potential for some morning mix of snow/sleet followed by steadier rains this afternoon and evening across the region as the low pressure system scoots east along the frontal boundary to our south.  Severe weather is possible across Virginia and parts of  Maryland this afternoon.   We should avoid that -- but a few rumbles of thunder are certainly doable across Philadelphia and points south.
