CoastalWx Posted April 11, 2013 Share Posted April 11, 2013 One of the more anomalous airmasses for mid April in quite sometime is about to give a good chunk of interior SNE and points north one last shot of winter. Link to comment Share on other sites More sharing options...

powderfreak Posted April 11, 2013 Share Posted April 11, 2013 Cloudy. 4,000ft...22F 1,550ft...30/18 750ft...35/17 Very cold column for this time of year with summits in the low 20s. Dry air continues to advect down with dews in the teens. Saint Johnsbury, VT currently with a dew point of 11F. Brrrr. Link to comment Share on other sites More sharing options...
dendrite Posted April 11, 2013 Share Posted April 11, 2013 Not sure exactly what the CON record low max is, but going back to 1921 it is 34F for tomorrow set back in 1976. They may have been colder in previous years though. It probably doesn't matter since the max should be around 5z tonight unless we can get some weenie precip in here early and evaporatively cool down. Looking good for some IP accums up here. The Euro is ice cold at 2m and keeps us at or below freezing the entire day. If most of that EC 0.75" QPF falls as sleet here then we're talking about 2-2.5" using the typical 3:1 ratio. There could be a little snow initially on the front end too before H7 goes to hell. The NAM has a little dry air initially in the H6-H7 layer so nucleation may suck to start out too. It should be a fun wintry goulash for the morning commute. Link to comment Share on other sites More sharing options...
dendrite Posted April 11, 2013 Share Posted April 11, 2013 BTW...on my way home I hit a few PL showers between exits 17-18 on 93. The atmosphere is primed for frozen. Link to comment Share on other sites More sharing options...

Oh its definitely cold out... on the mountain today it just had that January type look of slate gray skies and cold atmosphere with temps generally in the 20s and very dry air. Definitely felt like a winter event was on its way and it just got colder all afternoon. Dropping temps in the afternoon in April is impressive in itself.

Record low max at ORH was 34F...I thought we might have an outside shot at it but no chance with the delay until after 06z of the precip. We'll have a cheap midnight high for tomorrow.
