Today will feature the epitome of summer suffering weatherwise. WSW winds will continue to carry hot and humid air into the region. Temps currently (as of 8 AM) are in the upper 60’s to low 70’s with dew points in the mid to upper 60’s north and low 70’s south. Highs today will be climbing into the low to mid 90’s for most with some mid to upper 80’s in the far north and along the midcoast (Rockland could manage to stay in the low 80’s with the marine influence).
Morning fog could be dense for the next couple of hours before it burns off to full sun this afternoon. A few clouds are possible in the far north and one or two of those clouds could bring a brief shower but no widespread rain is expected due to the lack of a trigger. Dew points, as shown on the map, are quite stifling this morning. As the ground heats up and the atmosphere becomes a bit more mixed, warmer but drier air will filter down from aloft. This means that during the peak hours for temps, dew points will be slightly lower and vice versa. This will spare us widespread heat indexes of >100 but the difference will be a matter of a degree or two so regardless, it is looking to be quite hot. Heat advisories are up for southern NH and York County ME for the oppressive heat and the ME and NH coastlines are under an air quality alert for high ozone levels. The morale of the story? Today’s a good day to find the A/C and wait it out.
Showers and storms, some of which could be severe, are likely to bring at least some relief tomorrow evening but not after more heat tomorrow afternoon.
