Moderate Rainfall Friday Night-Saturday

Image
Hopefully everyone has a chance to enjoy the great weather today.  Rain will move into the region overnight leaving Saturday unsettled.  Sunday will be overcast with isolated showers.  Skies will begin to clear Sunday afternoon/evening and high pressure builds in for early next week.  I posted the other day about the potential for a rainy pattern to set up.  I still like that set up for the end of next week/next weekend.

Current Conditions 
Temperatures have climbed into the low 60s this afternoon away from the coast. The winds have also relaxed which is very welcome after yesterday
High pressure has slid offshore and will continue to move east this afternoon.  Tonight/tomorrows rain is driven by low pressure in the Great Lakes Here is the upper level support for the systems The Northeast radar shows this progressing nicely to the northeast There is a tornado watch for North Carolina and Virginia.  Southern New England will stay out of the severe weather but a few embedded thunderstorm…

Looking Ahead; End of April and Early May

There are several things to note from the two images.  First is strength of the cold anomaly in South Central Canada.  Second is the warmth in the last seven days in Alaska and the NW Territories of Canada. Third is the cool anomalies in Atlantic Canada and Greenland.   Why are these features important?
According to a 1950 report by Jerome Namias found here April and May tend to be the opposite it terms of weather; in fact the difference is second to only October and November.  He also concluded that the strength of the reversal can be tied to the strength of the Canadian cold pool.  This makes sense; if April is warm and May is cold then there must be cold air lurking to the…

Tuesday Weather Forecast

Image
Low pressure in the Great Lakes will continue to push towards the Atlantic coast this morning.  An associated warm front will push temperatures into the mid 60's as the sun pops out this afternoon.  
Current Conditions The Northeast regional radar as of 5 am  There are some heavier downpours embedded within this rain.  That will slow the morning commute so give yourself some extra time.  The 2 am surface chart shows the warm front ready to surge north as the low lifts through Central New England later today Temperatures are generally in the mid 40's, although temps are near 50 in SE MA Rainfall will end west to east between 9-11 am.  Winds will increase out of the Southwest with gusts as high as 25-30 mph.  Temperatures soar into the low to mid 60's.   Temperatures tonight drop into the low 40's/upper 30's.  Wednesday is dry and cooler.  Next chance of rain appears to be Saturday.  Have a good one
