An active pattern continues The parade of disturbances is lined up, but there is no real disruptor in the short term to bring relief from the humidity. We'll be dealing with a tropical rainforest environment with dew point temperatures wobbling between uncomfortable (65-70°) and oppressive (70°+) over the next ten days before a potential break. The daily chance for heavy rain showers and potential thunder, times of steamy heat, areas of fog over interior areas in the mornings, and the shorelines dealing with it off and on all day is what it is through the weekend and well into next week. Warm front moves into the region Wednesday A slight adjustment to the Weather Prediction Center's thinking on the flash flood threat, with partial credit to the lack of showers and storms than what ideas the models were selling on Tuesday. The images out of Vermont where over 8" of rain fell from the system that passed through Monday night were tough to see, and a flood watch is issued there and for Carroll, Coos, and Grafton County, New Hampshire with what is on the way through Wednesday night.  Wednesday 6 AM to Thursday Midnight - As we've seen all summer, the best chance for showers and storms is over the western foothills up into the Allagash. Eastern areas stay mainly dry for the day, with hit-or-miss showers for the south and MidCoast areas. Strong to severe storm potential remains on the discussion table. The rule of thumb is if the sun comes out, the thunder guns may come out. Damaging wind, frequent lightning, and torrential rainfall are the main concerns, but if a supercell develops, it may bring hail and a potential tornado. As I mentioned yesterday, I don't trust warm fronts, and I especially do not trust warm fronts with this much humidity around.  With the front approaching, breezier conditions are expected as compared to Tuesday. This keeps the coastal plain air stable and inhibit too much in the way of atmospheric drama, other than a chance dumper for the south and MidCoast. Fog may be an issue further up the coast. Another night of warm temperatures in the upper 60s to low 70s to start Thursday, with fog and a few showers around. Showers and rumbles for Thursday Thursday Midnight to Friday Midnight - Eastern areas that stay mainly dry Wednesday get their chance for showers and storms on Thursday. Chances for southern areas appear isolated. Humidity nudges up a bit more. Southern areas could hit 90° for highs, with the heat index pushing toward triple digits. Gah.
