Weather update

Heading in to work the Triad weather center this morning...passing along some 'stuff' for anyone interested...

These maps are pretty fresh off the NWS press...the first map below is a precipitation guidance for estimated totals, in this case through Sunday morning...If this were to verify, clearly the best chances for a good sledding snow will be east toward Raleigh/Wilson direction. Most of the Triad is left/west of the 0.25" liquid line (red). If you want to play the 'what if' game, let's say PTI airport got 0.2"...let's assume it all fell as snow...and let's assume it fell in the good ol' 10:1 ratio of " of snow:" of rain. That's 2" of snow. Wheee.

I was trying earlier to get onto the News 14 website but it was temporarily nuked...I trust it will be back up and running soon. At this time only Alamance County is in the warning area, and, honestly, that's marginal. The core Triad population centers are in the advisory, and the north and west periphery is in the advisory. Unlike Thursday's start with super dry air, we've held on to the moisture. Temps are in the upper 30s, with dewpoints in the mid 30s, so we won't lose much to evaporation. Especially in the advisory, I'm doubtful any rain will fall, just snow. But keep in mind, models indicate very little moisture to accumulate much.

The surface map is for 8pm this evening...showing the cold front along I-85 and pushing the precipitation eastward, where the switchover to all snow takes place with nice accumulations for, say, students at East Carolina in Greenville, NC.


I'll add to this as I see interesting information...not overly excited for this system in terms of a good snow, and we may well have news crews out in the field without a whole lot to talk about, at least for a while.

Stay tuned!
