From the WABI-TV5 & CW Forecast Center:
The cold front that is currently moving through Maine will become stationary just to our east this evening. Energy aloft moving east through the Ohio River Valley has caused a new storm to develop over the southern Mid-Atlantic Region. This new storm will move northeast tonight along the stalled front and bring rain back to our area late tonight and tomorrow morning. The rain will taper off from southwest to northeast during the morning and early afternoon hours tomorrow as the storm lifts off to our northeast into Nova Scotia. A bit of afternoon sun tomorrow will allow temps to once again warm to above normal levels.
Weak high pressure will produce a partly sunny start to our weekend Saturday, with temps still running a few degrees above normal. A few showers may develop here as a cold front moves east through our region Sunday. Temps will begin to turn cooler behind the cold front Sunday, with the trend towards chillier weather continuing next week as a series of troughs sweeping through the northeast brings progressively cooler air to Maine. A storm system Tuesday will likely bring some rain showers too much of New England. A northwest breeze on the backside of the storm will likely usher the coolest airmass of the fall so far into our region for later Wednesday through Friday.
Tonight: Becoming cloudy, with showers developing along with patchy fog and low temps in the upper 40s to low 50s.
Friday: Morning showers then partly sunny, with high temps in the upper 50s to mid 60s.
Saturday: Partly sunny, with high temps in the mid 50s to mid 60s.
Sunday: Variably cloudy, with a few scattered showers likely, breezy and cooler, with high temps in the 50s to low 60s.
Monday: Partly sunny, breezy and cooler, with high temps in the upper 40s to mid 50s.
Tuesday: Becoming mostly cloudy, with showers likely developing and high temps in the mid 50s to low 60s.
