DAYS 1-5 (JULY 10-14)

We’re in the final hours of this bout of more humid and very warm weather as a cold front slips southward across the region today. The timing of this front is early enough so that the air mass will already be starting to dry out and stabilize north of I-90 by midday, with the greatest chance for shower and isolated thunderstorm activity occurring from the I-90 belt southward this afternoon and early evening. A westerly flow aloft may keep a canopy of cloudiness over much of the region from midday to early evening, but does set up the potential for a colorful sunset in some areas as it departs later on. (These colorful sunset predictions are iffy and highly dependent on location and fairly precise timing of clearing and your location relative to the edge of the cloud deck). Surface high pressure from Canada and a weak trough aloft combine to bring our region fair and pleasant summer weather Saturday through Monday. By Tuesday, the surface high drifts to our south, allowing it to heat up with more humidity. As previously mentioned, I’ll monitor upstream disturbances coming over the top of a high pressure ridge to our west for cloudiness (and perhaps a shower / t-storm threat) that can mess up the forecast as we head toward early next week, although I’m not expecting any big change potential at this time.

TODAY: Most sun morning. Least sun afternoon. Potential for showers and a possible thunderstorm mainly I-90 belt southward afternoon to early evening. Highs 74-81 South Coast, 82-89 elsewhere. Dew point around 70. Wind SW 5-15 MPH, a few higher gusts, shifting to NW from north to south.

TONIGHT: Clearing except patchy ground fog. Lows 63-70. Dew point falls toward 60. Wind NW up to 10 MPH.

SATURDAY: Sun and passing clouds. Highs 78-85. Dew point in 50s. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 58-65. Dew point in 50s. Wind W up to 10 MPH.

SUNDAY: Lots of sun. Highs 78-85. Dew point in 50s. Wind W 5-15 MPH.

SUNDAY NIGHT: Variably cloudy. Lows 61-68. Dew point nearing 60. Wind SW up to 10 MPH.

MONDAY: Partly cloudy. Highs 82-89, cooler South Coast. Dew point around 60. Wind SW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 65-72. Dew point 60+. Wind SW 5-15 MPH.

TUESDAY: Partly cloudy. Highs 86-93. Dew point 65+. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 15-19)

Front moves through with a shower and t-storm chance July 15 with a leaning toward first half of day. Watching shower potential from passing disturbance about July 17 otherwise mainly dry late next week. Temperatures show some typical variability but should average not far from normal for this time of year.

DAYS 11-15 (JULY 20-24)

No big changes to the outlook here. Generally seasonable pattern overall, but can contain a brief shot of hotter weather and a shower / t-storm chance when a disturbance or front passes by. Too far out to know timing on any of that potential.
