Summery Week Expected (July 25-29)

Most of the week looks summery with possibly a slight break in humidity mid-week. Friday and into the weekend looks cooler but stormy. Let’s break it down:

Monday (July 25) high temperatures should reach into the 90s for most. Coastal areas could be held in the mid-to-upper 80s. Skies should be mixed and humid with a chance for severe thunderstorms in the evening. Wherever the sun breaks through during the day will get a boost in humid feel. Heat indices could break into the 100s. Winds should be light out of the W/SW. Overnight lows should fall into the 70s for most, maybe mid-to-upper 60s for NNJ elevations.

Tuesday (July 26) high temperatures should reach into the 90s for most. Coastal areas could be held in the mid-to-upper 80s. Skies should be sunnier with less humidity. Heat indices could flirt with the 100s. Winds should be light out of the W/NW. Overnight lows should fall into the 70s for most, maybe mid-to-upper 60s for NNJ elevations.

Wednesday (July 27) high temperatures should reach into the 90s for most. Coastal areas could be held in the mid-to-upper 80s. Skies should be mostly sunny with only an isolated chance for a shower/thunderstorm. Heat indices could break into the 100s. Winds should be light out of the NW with the exception of a developing E sea breeze for coastal areas (possible thunderstorm trigger). Overnight lows should fall into the 60s for most, maybe just the lower-70s for the coast.

Thursday (July 28) high temperatures should reach into the 90s for most. Coastal areas could be held in the mid-to-upper 80s. Skies should be partly sunny with humidity starting to return. Heat indices could break into the 100s. Isolated afternoon-evening showers/thunderstorms cannot be ruled out. Winds should be light out of the S/SW. Overnight lows should fall into the 70s for most, maybe mid-to-upper 60s for NNJ elevations.

Friday (July 29) high temperatures should have trouble escaping the 80s for most. 90 is possible for interior areas. Skies should be mostly sunny with again, the chance for isolated afternoon-evening showers/thunderstorms. Winds should be light-to-breezy out of the S/SE. Overnight lows should fall into the 70s for most, maybe mid-to-upper 60s for NNJ elevations.

Marine: Ocean surface temperatures along the beaches remain in the low-to-mid 70s except for an area of mid-to-upper 60s from Atlantic City to Ocean City (due to SW flow upwelling). Wave heights should generally be 1-3 feet this week with Tuesday possibly seeing some heavier surf (3-6 feet). This will correlate with a change in wave direction from E/SE now to S/SE for Tuesday and then back to E/SE by Wednesday. This should be in correlation with a  temporary Bermuda High pressure positioning establishing the southerly wave flow.

Stargazing: Monday and Tuesday night would likely be the best being just after a frontal passage (if clouds can cooperate). The moon will transition from waning gibbous to morning crescent and rise a little later each night. Tonight, it rises just before 10PM. By the end of the week, it will rise after midnight. Therefore, there will be less lunar light pollution for stargazing this week than last. Next week stargazing will be optimal with the new moon phase if we can get a clear night.

An early look at the weekend indicates a cooler (highs in the 80s) but unsettled/stormy period, possibly driven by the close passage of a synoptic low pressure system. We could sure use widespread synoptic rainfall. The frontal/mesoscale rainfall we’ve been having is not cutting with respect to drought interests. The entire weekend should not be a washout. I’ll have a much better handle on timing in a few days. Otherwise have a great week and be safe! JC
