Hello everyone, after a 1 week vacation we are back up and running here , I just want to start off with sending my prayers and condolences to those who were impacted, injured and those who lost their lives during the horrific bombing of the Boston Marathon on Monday.
Over the past 7-10 days or so we have entered a more spring like weather pattern after a very cold March and chilly, winter like early April, we have seen a trough or dip in the jet stream dominant in the western US which has led to transient ridges and some nice warm ups here in the eastern US
This pattern will continue through Friday with a continued building ridge over the east and continued temperatures above normal and overall nice weather conditions
This morning we had a cold front attempt to cross the area with som,e clouds and showers, but weakened and dissipated before it could do so thanks to the building ridge over the east so the warm air mass will remain in place uninterrupted with highs today ranging from the upper 50s along the coast to the mid to upper 60s elsewhere with plenty of sunshine this afternoon, lows tonight will fall into the low 40s NE PA to the upper 40s/ low 50s along the coast
We do have a warm front currently around the Tennessee River Valley, this will move north and cross the area tomorrow night into Friday , so tomorrow will have more clouds with the chance of some isolated showers, it should be a mainly dry day and still very comfortable temperatures with highs in the mid 50s to low 60s , lows will only fall a few degrees from the daily high Thursday night
This warm frontal passage will lead to a surge of warmth for Friday , with temperatures expected to be in the lower to mid 70s widespread besides along the immediate coast where temperatures will be held in the 60s with a south wind off the Atlantic, with a mix of sun and clouds becoming more clouds in the afternoon with increasing chance of those pesky isolated showers again , along with increasing south-southwest winds but it should be a relatively nice and dry spring day
Friday night into Saturday a potent cold front will come through the area as a strong area of low pressure passes well to the northwest
The main impact from this cold front will be in the overnight hours of Friday into the early morning hours of Saturday with heavy rain, wind and thunderstorms
There will be a strong jet streak along and ahead of this front , this along with a surge of warmth will lead to a somewhat unstable atmosphere ahead of this front which will lead to the chance for strong thunderstorms to develop, these thunderstorms will be capable of brings the strong winds aloft down to the surface so sustained winds of 20-30 mph can be expected with gusts possibly exceeding 50 in thunderstorms, which will also be capable of producing small hail
A general 1/2 inch – 1.50 inches of rain is expected with this system, which will clear out by late Saturday morning , and will usher in a much cooler air mass with temperatures below normal Saturday through Monday, highs in the upper 40s to low 50s NE PA to the mid to upper 50s along the coast and lows in the mid 30s NE PA to lower 40s along the coast, our next storm system will approach Tuesday into Wednesday with perhaps another surge of warmth and another round of showers, thunderstorms and wind possible.
