A weakening frontal boundary slowly presses eastward today as a warm front brings above average temps for this time of year. High level clouds & isolated sprinkles well ahead of the front now invading the northernmost portions of our forecast area but widespread measurable rainfall will be delayed until tonight/Wednesday. Thunder, hail & strong gusty winds are not out of the question tonight/Wednesday as plenty of warm air & moisture will be available Wednesday. But weakening dynamics along the frontal boundary lend to marginal chance for this to be realized. Still expecting round about an inch of new rainfall with potentially heavy downpours possible at times as this system combines with coastal low pressure lifting north along the Eastern Seaboard. Then cooler air on the backside of the front will bring chilly & breezy conditions with possible wind advisories into Thursday as the front passes. A few light raindrops linger into Friday/Friday night with highs reaching the mid 50s & lows falling into the low 40s/upper 30s. Will need to watch frost/freeze potential towards the end of the week. Snowfall chances will be very light and limited to the highest terrain. High pressure & sunshine will dry things out with mild temps by Saturday/Sunday.
