Area forecast discussion, Jul 28, 1:55 PM EST, 10 minutes before
Area Forecast Discussion National Weather Service Gray ME 255 PM EDT Sun Jul 28 2019 .SYNOPSIS... A weak frontal boundary will move south across the region this evening, generating showers and thunderstorms. The front won't result in much of an airmass change though. Expect to see gradually increasing temperatures and humidity through Tuesday when another frontal boundary moves through. This front will bring another chance of showers and thunderstorms Tuesday evening into Wednesday with cooler air arriving behind it for the last part of the week. && .NEAR TERM /THROUGH TONIGHT/... Primary focus of the near term will be on showers and thunderstorms moving across the forecast area. A weak surface boundary is dropping south out of Canada this afternoon and will wash out over the coastal plain later this evening. Strong surface heating and relatively high surface dewpoints is resulting in MLCape values of 1000-1500j/kg. That being said, there is very little directional or speed shear aloft. A weakening mid level shortwave is moving through the area as well. This all combines to produce a decent environment for convection, but not a strong enough environment for widespread severe thunderstorms. Expect gusty winds to by the primary threat and SPC has placed us in a marginal area for severe. One or two cells may develop enough structure to warrant a warning this evening. As the upper level support for storms races off to the east this evening, expect to see storms quickly die off before midnight. Due to the remaining low level moisture though, we will likely see areas of fog develop again tonight in favored valley locations. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... Upper level flow becomes more zonal on Monday morning with a weak mid level ridge building over northern New England. This should be enough stability to keep the weather quiet. Upper level flow shifts to the southwest overnight on Monday, resulting in warmer temperatures moving in and prepping us for the next system. && .LONG TERM /TUESDAY THROUGH SUNDAY/... A frontal system will approach from the west on Tuesday. Strong southwest flow ahead of the system should allow for the warmest temperatures of the forecast period. Locations in southern New Hampshire and the coastal plain of Maine will see temperatures climb into the lower 90s, with 80s further inland. The frontal boundary is relatively slow moving and looks like it should cross the region during the overnight hours Tuesday night and into Wednesday. This timing would keep the weather primarily showers with isolated thunderstorms and should limit any severe thunderstorm activity. Once the system clears the coast on Wednesday, high pressure and cooler temperatures prevail for Thursday and Friday before another system arrives on Saturday. The system on Saturday currently looks like it should move out of the mid-Atlantic states on Saturday and across the region by Sunday morning. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... Short Term...Showers and thunderstorms this evening will produce some areas of MVFR. There will likely be some valley fog tonight as well that will generate some IFR/LIFR conditions at a few of the TAF sites. Otherwise, tomorrow looks mainly VFR. Long Term...Mainly VFR conditions expected, with MVFR/IFR conditions expected on Tuesday as a frontal boundary moves through. && .MARINE... Short Term...No Flags but winds may briefly approach sca levels this evening. Long Term...No flags expected. && .EQUIPMENT... The Sugarloaf NWR transmitter is off the air until further notice. This will be an extended outage as the tower, which was severely damaged in a winter storm, is rebuilt. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None. MARINE...None. && Pohl
