 An upper low over western Quebec passes through the state to start the week. As the temperatures warm in the morning, clouds pop up and bring the risk of isolated to scattered showers with the slight risk of a thunderstorm in the afternoon.  Noted in the Sunday 8 PM weather balloon launches by the Caribou & Gray weather offices, the freezing levels then ranged between 9,000 – 10,000 feet. With just enough convective available energy around, the steep temperature rates may produce isolated low-capped storms capable of producing small hail, in BB to pea size form.  As the sun sets, the atmosphere cools, the sky turns mostly clear, and the shower/storm threat dissipates. Overnight low temperatures fall back into the 50s for most areas, with some upper 40s possible for the protected valleys in the western mountains.
TUESDAY appears to be the best chance for an all-dry day across the state, but I can’t rule out an isolated shower over The County. A wave on the backside of the upper-level trough may stir instability up. Temperatures appear to run a bit warmer as the cold pool aloft moves northeast. High temperatures range in the 70s to low 80s. WEDNESDAY THROUGH FRIDAY… The upper low that passes through here on Monday connects with a stronger upper low over the North Atlantic. Thanks to blocking near Europe and the strong ridge to the south, it hits road block and the gets shoved back to the southwest toward Maine. This brings a backdoor cold front (BDCF) and increases the risk of mainly afternoon showers and possible thunder through the remainder of the week. Time will tell if that may linger into the weekend. Yeah, it’s Monday. Let’s get after it and get it over with. Thanks for your support! – Mike |
