Friday July 1 2022 Forecast (6:42AM)

DAYS 1-5 (JULY 1-5)

On this first day of July, many people begin a multi-day holiday weekend, so basically we treat this 5-day period like it’s one extended weekend, and weather-wise, it’s going to be a pretty good one as far as summertime weekends go. No, it’s not going to be perfect. We have some heat in the forecast, some thunderstorms in the forecast, and some wonderfully warm and dry weather as well. High pressure slides offshore today and in comes the heat. But the humidity is not going to jump up right away. That’s actually going to spike later today, mainly this evening, tonight, and into Saturday. On the heading edge of this “dew point boundary” we may see an isolated thunderstorm or two fire up somewhere in the WHW forecast area this afternoon, but I would not cancel any plans over it. Just keep an eye out for building clouds and if you hear thunder, be ready to move to a place of safety while any storm passes by your area. The most likely time for this to happen is mid to late afternoon. Tonight, the storm threat vanishes in the evening but returns overnight as a disturbance moves through the region. Another disturbance brings the chance of a couple morning showers and thunderstorms Saturday as we sit in the soupy air. And finally a cold front will slice across the region from northwest to southeast Saturday midday and afternoon, finally exiting via the South Coast during the evening hours. This front will trigger the best chance of thunderstorms, in terms of coverage and intensity, but it will likely take the place of one line or a couple line segments. Any of these storms can become strong to severe, so anybody with outdoor plans should be very aware of the weather Saturday. From Saturday evening on through Sunday as well as Independence Day Monday, it’s “clear sailing” with a Canadian air mass arriving and providing great weather. When we get to Tuesday, we’ll be eyeing the approach of a disturbance from the northwest which at least brings clouds, and perhaps a shower and thunderstorm chance. Some fine-tuning is needed for this, as quick-moving disturbances are hard to time beyond a couple days in advance.

TODAY: Sun/cloud mix. Isolated thunderstorms mid to late afternoon. Highs 88-95, cooler South Coast. Dew point ranging from middle 50s north and west to middle 60s South Coast through early afternoon, rising to middle to upper 60s all areas later. Wind SW 5-15 MPH, higher gusts by late in the day.

TONIGHT: Partly cloudy evening. Variably cloudy overnight with isolated to scattered showers and thunderstorms possible. Lows 67-74. Dew point upper 60s. Wind SW 5-15 MPH.

SATURDAY: Variably cloudy. A shower or thunderstorm possible early, then a passing shower or thunderstorm during the afternoon and early evening from west northwest to east southeast across the region, with any thunderstorms potentially strong to locally severe. Highs 85-92, cooler South Coast. Dew point rising to upper 60s to around 70 through early afternoon, then falling slightly especially in northwestern areas by late day. Wind SW 10-20 MPH except variable with potential strong gusts near storms, shifting to W from northwest to southeast later in the day.

SATURDAY NIGHT: Variably cloudy. Evening showers and thunderstorms possible, mainly South Coast. Areas of fog especially South Coast. Lows 62-69. Dew point falling to upper 50s north of I-90 but staying in 60s to the south. Wind W 5-15 MPH.

SUNDAY: Lingering clouds South Coast early, otherwise mostly sunny. Highs 80-87. Dew point middle to upper 50s except lower 60s South Coast early. Wind NW 5-15 MPH.

TUESDAY: Increasing clouds. A shower or thunderstorm possible. Highs 76-83, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JULY 6-10)

Two disturbances should move through the region with a west to northwest flow during this period bringing opportunities for showers/thunderstorms for relatively brief periods of time, and some variable temperatures but not straying that far from normal.

DAYS 11-15 (JULY 11-15)

Weaker westerly flow and more high pressure to the south should allow for warmth and somewhat higher humidity to be the rule but with limited shower and thunderstorm opportunities.
