Afternoon showers possible through the Independence Day weekend
Thursday, June 30, 2022
Cloudy skies, temperatures around seventy degrees and relative humidities above fifty percent are over the Steamboat Springs area this Thursday mid-afternoon. There will be good chances for rain later today and overnight, with those chances being relegated to the afternoon and evening and diminishing, but certainly not disappearing, for the duration of the long Independence Day weekend.
A ridge of high pressure is forecast to rebuild over the Intermountain West this weekend while an area of low pressure currently near the Gulf of Alaska is forecast to strengthen as it elongates southward along the West Coast. Some energy from the west being dragged eastward by the southern edge of a storm rotating through the Great Lakes will combine with the high humidities over our region for good rain chances this evening and overnight.
Winds from the south ahead of the West Coast storm will encourage the ridge of high pressure to rebuild over the Rocky Mountains this weekend, and the combination of those two features means the monsoonal moisture tap from the south will continue through the holiday weekend. Because the ridge of high pressure will help steer upper level energy around our area, we will be dependent upon the heat of the day to create an unstable enough atmosphere for the usual afternoon and evening showers.
Weather forecast models agree the West Coast storm will stay to our west as any eastward progress will be met by stout resistance from the ridge of high pressure over our area, though at some point next week it appears the West Coast storm will move to the east far enough to bring drier air overhead. So while it appears the atmosphere will dry and warm after the weekend, there is uncertainty with respect to the timing. Stay tuned as I’ll know more about that by my next regularly scheduled weather narrative on Sunday afternoon.
