Wet bulb and evaporational cooling is gonna be wild! RNK's map had you starting at 3-5 and me at 5-7. Looks like precip is moving in more quickly than anticipated.

That's pretty right on with what my gut says too. I've been telling everyone 4-8", but I'm leaning toward the higher side of that range. 9-10" definitely not out of the question, but 12z runs reversed the nice push we got on 0z. I still don't really trust big ratios on the front end. Evening stuff tomorrow? That's fluff. 1 Link to comment Share on other sites More sharing options...

WEATHER53 Posted Sunday at 05:58 PM Share Posted Sunday at 05:58 PM If I do the dp vs temp spread for accurate BWI/IAD/Andrews it’s 31/5 now and with mild overrunning we will get about 33% drop rate so that’s puts us at 23/24 when 90%rh and snowing steady to moderate Link to comment Share on other sites More sharing options...

psuhoffman Posted Sunday at 05:59 PM Share Posted Sunday at 05:59 PM 26/10 smoking cirrus on the whole the 12z suite was a bit of a letdown for the MD line. Northern guidance went south and south went north. But I was expecting we would gain some ground this close. Confluence isn’t really that strong imo the SW just isn’t as amped and so the mid level jet is directed more latitudinally which limits the ability of the gulf moisture to punch north into the flow as effectively. But it’s still super close for the area and a 20 mile last minute shift or an extra .2 qpf is common and that’s all we need so I’m holding steady despite not seeing what I wanted 12z. RAP is trending north again and latest HRRR was pretty good. ETA: I saw some posts expecting the gradient to be less severe but it will be. Think back to Jan 30 2010. Westminster got 6”, the PA line 2-3 and 10 miles into PA not a flake! Jan 2019 10 miles south of me got 6”, I got 2” and 10 miles north nada. We just have to hope that cutoff ends up just north of the PA line and not just south of it. I still lean that way. 7 Link to comment Share on other sites More sharing options...

Best cold-ENSO pattern since 1996. There’s a reason why people said that. 1 Link to comment Share on other sites More sharing options...

WxMan1 Posted Sunday at 06:13 PM Share Posted Sunday at 06:13 PM 32°F in Crofton MD right now, high clouds moving in. Over the years I've come to trust the ASOS/AWOS dewpoints over anything else, so I'm gonna go with the 5°F Td at both BWI and Annapolis. 2 Link to comment Share on other sites More sharing options...

Weird. My station has sat near my pool for 10 years now and I’ve never noticed a difference compared to other weather stations nearby.

I was referencing those storms as similar setups wrt a sharp northern snowfall cutoff. Models still struggle with pinning down the exact location and qpf with the h7 banding near the northern periphery of these type waves. They did it just last winter in Feb. The banding shifted north at the last minute and places forecast to get 1-3” in central PA got 6-12”! 1 Link to comment Share on other sites More sharing options...
