What a beautiful stretch of weather we’ve had for the past 4-5 days. I don’t think we could have asked for better weekend conditions, however, there is some poor weather on the way. The timing for this event seems to be Tuesday evening into Wednesday morning.
An upper level low pressure system with an associated occluded frontal system will approach Tuesday and pass through the area on Wednesday morning. This system will have a large amount of moisture associated with it, and could drop about 1-3 inches of rain during this time period. Also, it will be moderately muggy on Tuesday as this system approaches due to a southerly wind. On top of the rain expected, there is also a chance for some severe weather on Wednesday morning. Along with the moisture and lift that will already be in place, there is also a good amount of wind shear and a small amount of CAPE as well. These 4 ingredients could combine to allow for some severe thunderstorms to develop during the Wednesday morning rain event.
A quick rundown of the event:
Rain starting Tuesday evening around 5 PM.
Heavier rain beginning 3 AM-5AM.
Rain will taper off around 2PM
A total of 1-3 inches of rain
Also a possibility for some flash flood watches/warnings
UPDATE: As of 4:01 PM the National Weather Service has issued a Flash Flood Watch for the entire state of Connecticut. The watch is in effect through Wednesday Afternoon.
The next few days following the rain will be much like the ones leading up with it, pleasant with a good dose of sun.
