After a fiery day, temps shot down last night after the cold front passed....and the Texans went home. Pretty mellow today as we hovered in the mid 40s with a sunny cameo.
Quiet stretch coming up. One that will see the same-ol-same-ol: cold shot of air, slow moderation, close to 50 by week's end. Nothing new there...
...or maybe there is.
A subtle frontal passage on Saturday morning may be the only signal of the coming pattern change. At first, it's just enough to get your attention: dropping our high temperatures from near 50 on Friday to the mid 40s on Saturday. Nothing of note there, right? Ah, but the devil's in the details. Let the record show that the front dropping in is connected to a storm backing up over Labrador, which is a result of a return of...
...the Greenland Block.
If you recall, in year's past, this term meant snow (most of the time). Far be it for me to deny that the threat is comin' back around again.
Whereas I was full of denial yesterday, today I am beginning to believe, Morpheus. We surely aren't heading into a deep freeze, but our temperatures will be just cold enough for snow.
As of late, every time we get a storm, it tracks to our west into New York or Vermont, the temperatures rise, and we see rain. This block over Greenland means that the cold won't pull out. It will be pinned down across New England, forcing the storms to travel just off of Long Island, Martha's Vineyard and Nantucket. This doesn't completely guarantee snow over ALL of our viewing area, but it throws the odds in favor of more white than wet.
Certainly there are fine points to the forecast that need to be worked out, but consider this an early heads up for the Sunday-Tuesday time frame.
