We will squeeze out one more decent day Friday before some changes are ahead just in time for the weekend. High pressure slides offshore with a milder SW wind at the surface Friday. Morning sunshine will give way to increasing cloudiness fairly quickly. So expect a more grey appearance to the sky during the afternoon as high-mid latitude clouds flow over us. Highs will generally range 70-75 degrees by the afternoon.
A warm front approaches New England Friday night and stalls over southern New England. Scattered showers will ride along this front across the north country. The best timing of showers will be between 3 AM and 9 AM Saturday. With a front stalled over us, Plenty of clouds will linger Saturday with still the risk of shower of a few widely scattered showers. Where this stalled front sets up will have huge implications to how cool or how warm we will be Sunday. It has been a struggle to nail down Sunday's temperature because of this complex set up. Today, it appears the stalled front will shift just east enough on Sunday that we will get into the warm sector with partly sunny skies and highs in the 70's near 80. Meanwhile, Maine will be much cooler with the onshore winds. Stay tuned as just a few miles mean the difference from a fall feel to a summer feel.
So I am leaning optimistic Sunday, but would have to lean a bit more pessimistic Monday. Another backdoor front will slide south from Maine as high pressure strengthens over Nova Scotia. This front will push through New Hampshire bringing a cooler windshift and temperatures back into the 60's and 50's at the coast. Along with the cooler air, an increase of low clouds will also accompany the backdoor front and spread across New Hampshire. The high will supply low level dry air to make Monday decent enough for some partial sunshine. Just as quickly as the high moves in, it will move out with another front pushing through Monday night and Tuesday with another chance of showers. Cooler, breezy conditions return for the midweek with sunshine with building high pressure
None of these showers will be steady enough to put a dent in our recently dry conditions. The US Drought Monitor just put New England in abnormally dry conditions. In regards to drought status, we are still at low levels...but if this trend continues we may see some bigger problems down the road. New England always has a way of balancing out though from one extreme to the other.
