The story of the three upper-low amigos continues. The first one is punching the strong ridge offshore today. The second amigo is dipping into the northern parts of the Midwest as the day progresses, then drags a cold front through the region Wednesday into Thursday. The third amigo shoves the ridge further into the Atlantic by the weekend and will hold it there for several days. TUESDAY MORNING SHOWERS/RUMBLES PASS THROUGH, and the rest of the day appears to avoid rainfall activity. Note that I did not say “dry.” The dew points are expected to rise a few degrees more today. We’re just going to have to sweat this thing out. WITH THE RISE OF DEW POINTS comes the expansion of the heat advisory. Time will tell if Bangor and Portland hit 90°, but with dew points in the 70s, heat indices in the 90s to low 100s are a given with this tropical air mass. ANOTHER NIGHT WITH SHOWERS / STORMS POSSIBLE as another mesoscale convective system (cluster of thunderstorms) passes through the region. Dew points continue to rise. Overnight “lows” could break records again, with a few more areas bottoming out in the 70s by Wednesday morning. This cluster coming through may bring more chances for rainfall than the one that passed through early Tuesday. HIT-OR-MISS SHOWERS / STORMS is the main theme through Thursday. Some areas could get hammered with 2-3” of rainfall, which may cause localized flash flooding. Other areas may escape without a drop. With a dry but warm pattern evolving starting this weekend, rain chances appear to be scarce through the end of the month. SEVERE CHANCES WEDNESDAY appear isolated. There is enough spin where there is a damaging wind component. This risk is cloud cover dependent, which will dictate how far temperatures climb. It’s a wait-and-see situation. TIMING FOR THE FRONTAL BOUNDARY TO BRING RELIEF appears to be Wednesday night. Given the amount of moisture around, it will take time for the air column to dry out. The north and mountains dry out sooner. It may be overnight Thursday into Friday morning before the coastal plain and shorelines see dew points drop into the 50s to low 60s. THE WEEKEND looks stellar. It appears warm, but comfortable. Humidity may return later next week. Always have MULTIPLE ways to receive weather alerts.
