CoastalWx Posted February 14, 2021 Share Posted February 14, 2021 Difference this time around is the SE ridge. That hasn’t been around really this year. So now you have a SE ridge, gulf wave, and some energy trying to phase just a bit. Link to comment Share on other sites More sharing options...

SnoSki14 Posted February 14, 2021 Share Posted February 14, 2021 Don't see why Tuesday won't keep trending warmer. Strong SE ridge, no high whatsoever. Nothing to keep the CAD in place beyond current snow cover. The system is weak overall and moves quickly so it won't be a big torchy cutter or anything.

That's how HQ wants us doing it now, even though anecdotally the Northeast has been radial forecasts. I suspect until we can iron out a new criteria for warnings, that's going to lead to some eye popping forecasts for fairly "routine" ice storm amounts.

ORH_wxman Posted February 14, 2021 Share Posted February 14, 2021 This could be pretty icy over the interior. Gotta watch for the mesolow too. Some guidance is trying to poke a mesolow up to the northeast. Not all guidance (NAM doesn’t really have it but rgem and to lesser extent euro)....but if we pop that mesolow up into CC bay and northeastward, then it’s goodnight for warming above freezing at the sfc at least to like 128 and maybe even a little closer to coast.
