Flash Flood Watch Issued Today & Friday

A anomalous low pressure system will cut up through the Appalachians keeping most of New England in a wet pattern.  While some of the storms are bound to be hit or miss the air mass is very tropical and the ground is saturated.  Therefore the National Weather Service in Taunton has issued a Flash Flood Watch for all of Southern New England (except Cape and Islands)
A stationary boundary to the north will help usher multiple storms into New England.  Surface low pressure is developing in the Ohio Valley.   At the upper levels the low has not "cut off" as of yet but that will happen later today/tonight.  As of this morning a shortwave was pressing through the Ohio Valley Here is the amount of moisture available in the air.  We call this Precipitable Water, or PWATS A batch of 2 inch PWATS is just offshore and moving NE.  This will be the main threat with any embedded thunderstorms along with frequent lightning.  Winds and hail appear to be a marginal at best threat today in So…

Muggy with Severe Thunderstorms

Although today will not be as warm as Monday and Tuesday the dew points will remain in the mid to upper 60's across most of Southern New England and thunderstorms will be possible again.  No this is not a recording and the thunderstorms will be more numerous as there is a trigger for the storms today.
The main threat will be damaging winds ( > 58 mph)Short Term Forecast/Observations Temperatures are off to rocking start with the majority of the region south of Worcester already in the 70's The rest of Southern New England is still in the upper 60's.  This morning it is going to be tough to rely on the models as they are forecasting a back door cold front which never really goes well.  The cold front should back across the Maine/NH seacoast during the midday hours.  How far it gets in MA is important as to where the best severe thunderstorm potential develops.  Visible satellite shows some broken clouds over SNE In areas in which the clouds and fog burn off quickly this…

More Heat, Humidity, and Thunderstorms Today

Oppressive heat and humidity will continue to dominate our weather in New England.  With these conditions comes a risk of thunderstorms some of which may be severe.  There were quite a few severe weather reports yesterday in the northeast
The threat today should be slightly further north but several areas will get hit again today especially in Southern VT and NH.  The NH and ME seacoast have been routinely pounded by thunderstorms in the past few weeks Damaging winds and large hail are the biggest things to watch.  Current temperatures are in the 60's Even nastier are dew points already in the low to mid 60's Temperatures will quickly rise into the 80's and low 90's this afternoon The simulated radar around 6 PM shows a nice cluster of thunderstorms in Western New England. Will get back to forecasting the medium range tomorrow have a good Tuesday.

Hot and Humid Today

Hot and Humid weather will dominate over the next few days.  Brief forecast today
It is a mild start with temperatures already in the low 70's in a lot of places.  Temperatures are forecast to rise into the low 90's Dew points will be in the low to mid 70's There is a slight chance of thunderstorms this afternoon Any thunderstorm activity will blossom around 2 PM.  Western New England has the greatest chance at seeing something severe.  There will be a lot of fuel to work with, just not much of a trigger.  There may be a weak trough extending from low pressure in Quebec so I'll watch the radar.  Mild night tonight and temperatures will soar back into the upper 80's low 90's tomorrow.  There is another threat of thunderstorms tomorrow.  Have a good Monday

Happy Summer!

Summer officially began at 104 am this morning and there is some hot and humid weather in the forecast.  It does not appear to be a permanent shift towards hot, humid, and relatively dry air.  However the weekend looks great in Southern New England despite a small chance at shower tomorrow afternoon.  Stay south this weekend as the rain will be falling in Northern New England in association with a frontal boundary.

Short Term Forecast/Observations
A cold front is present in Southern Ontario
Behind the front temperatures are very chilly this morning but here in Southern New England most are running in the mid to upper 50's Here is the current 500 mb set up
This ridge will continue to spread towards the east coast.  Sunday and Monday look like the best bets to be near 90.  Today however temperatures climb into the low and mid 80's.  Urban centers and valleys are in the mid 80's, rural and higher elevations will be in the lower 80's. Overnight low temperatures stay in the …
