Per SPC mesoanalysis, there's a pretty solid are of instability cresting the Allegheny Front.- 1,935 replies

In tropical situations, it can be useful to use the virtual temp at the sfc instead of the dry bulb temp. Using it can represent CAPE better in such environments (virtual temp increases CAPE). 76 dew point is nothing to shake a stick at! Don't need too much heating for things to go and go well w/ that kind of juice.

Use NAM MOS and HRRR together and you knew when the flip from SN -> IP -> RA would occur 90% of the time. That combination consistently schooled the GFS and Euro inside 30 hrs.- 1,935 replies

Slightly wet ground. Is this it? Yesterday's forecast was for a half inch today and up to an inch tonight. LOL This has been a recurring trend with the forecasts here for months.

Yes, the NAM has some uses. It handles CAD much better than the GFS, as one example and its MOS reflects that. But the HRRR handles CAD well, so no loss there. Since it has more vertical levels than all the global models, its should handle mix zone better and we are used to that. But again, the HRRR and now RRFS should effectively replace that skill (eventually). Losing some for other gain happens. I recall NHC objected to an upgrade of the GFS some years ago b/c it was clearly shown that the upgrade made TC skill less for the EPAC basin. The upgrade was done regardless. So it's hard to please everyone!

Got the Stephen’s city treatment so far today. Not even 0.1”, way less than most mesonet stations in central MD

2026 Mid-Atlantic Severe Storm General Discussion

Not the thread for this question, but is the conversation for it. I understand turning the NAM off for convective season, however, I don’t understand turning it off for winter short term stuff. I would love to know why, I assume it’s something in how it handles thermodynamics and WAA, but the NAM is almost always the most correct model when it comes to refining the mixing line in synoptic scale winter storms. It just seems odd to turn off a model which has a very useful edge on all others, even if it sucks at a lot of other aspects; could at least compromise and run it before major storms on the east coast. Would love to know your thoughts on both why it surpasses the other mesoscale models in the mixing line placement and how to compensate for its disappearance come winter time.- 1,935 replies

It’s raining again today and rained yesterday. It’s rained almost every day the last 6 weeks. What a turnaround after a super dry first 6 months of the year

Looks like an El Nino tropical map to me

It did in 1997 just a few weeks earlier this go around. I don't yet know why but feel this will peak earlier than expected.

Last typhoon that hit East China warmed the SSTS off East Asia especially East off Japan.Still myself would rather to see the PDO right now to rise and not fall.We might be seeing a repeat of the pattern we are in as we get closer to end of August into Sept. That strong WWB ongoing along with the Rossbly Waves should really kick off some tropical storms in the PAC the next few weeks

76/76 now but breezes from the south have been more steady and the lower foggy haze is lifting. Also seing very bright patches as the clouds seem to want to break up. Little patches of thinner clouds are showing up on satellite. We shall see if this enhances anything. Air is thick- 1,935 replies

CFSv2 10 day run mean is still not backing off of a cold Feb in a large portion of the US, especially corridor from SE US to C Plains where most areas are a whopping 5-7.5F BN though I’d prefer Alaska and NW Canada be AN: Compare this to the same for Feb of 2024 from about the same 10 day mean in Aug of 2023:
