Winter will not quit

My forecast in February was for a warm March and a cold snowy April. The warmth of March is upon us, however Mother Nature is catching up for lost time, which means taking any chance she can get. Tomorrow night, confidence has exploded for a moderate or even heavy snow event. The NWS is now calling for 2 to 4 inches, however model guidence continues to support as high as 6 to 7 inches. Tomorrow highs will reach the low 50's, and Sunday the same, however in between, winter will grab onto the 3 to 5 hour period when temperatures are below freezing to dump an advisory level snowfall across most of the region. More details on this event are in the winter weather outlook page.

Temperatures will stay up in the 50s under partly cloudy skies with a few chances for showers throughb early next week.

Looks like Mother Nature will have a few tricks up her sleeve for April Fools Day 2007. I've been talking about this for quite some time now, and my confidence is growing for a significant storm to affect us during the first few days of April. It will likely start as rain will a burst of warm unstable air out in front. The midwest could see a severe weather outbreak as the storm develops, and New England could even get in on a few thunderstorms. Rain will change to snow through the second of the month. Right now, the GFS shows only a brief period of precipitation corresponding with below freezing temperatures, but not sure at this point. The Euro has jumped on board with a closed low in the midwest at day 9 with a 1035mb high in Quebec. The set up is right for what could be a major east coast storm.

I'll issue a preliminary forecast this weekend.

Temperatures will take a nose dive and wont come back up through at least the first week of April. We could see a few light snow events through this period.

West of the region, a -PNA induced ridge will keep warm temperatures in the midwest. The -PNA will mean temperatures below average in the Pacific Northwest. A considerable temperature gradient stationary across the Rockies could mean a prolonged period of severe weather as waves move south from Canada. A major severe weather outbreak could be in store around the 5th of April in the plains. That will push the ridge eastward and will bring warmth back to New England through the 15th.
