High pressure continues to dominate

Turning Warmer

A large area of high pressure remains parked overhead and will keep our overall weather pattern unchanging for several more days.

The one difference from day to day will be a continued steady increase in temperatures as the high slides off to the east.

Today will be the day we end up with near average temperatures as we transition from cool to warm. Highs will top out in the mid and upper 70s this afternoon.

Like yesterday, cloud cover will be scarce with a few thin wisps here and a couple small fair weather clouds there. Winds will remain very light with variable directions, usually having some sort of easterly component.

Humidity levels remain very low with dewpoints today down in the 40s. This is about 35% of the normal amount of moisture in the atmosphere for this time of the year.

Clear skies tonight will send temperatures back into the 50s, where they should stick through the overnight for all but a few isolated cold pockets.

Wednesday will see 80s return to the area with some typically warmer locations near I-90 shooting up above 85 degrees. Dewpoints will reach the low 50s, which is still very dry for June.

Skies will remain mostly sunny, though a couple more small fair weather clouds may be able to develop.

Thursday should be the last day of near-zero rain chances as temperatures continue to rise. Look for highs in the upper 80s for most with mid 80s in the higher elevations.

Hot and Humid with Storm Chances

By Friday, dewpoints will climb into the 60s and it will start to feel a bit sticky with the heat. Afternoon highs should again push into the upper 80s.

Late in the afternoon, a few isolated showers and thunderstorms should pop up. Many areas will not see rain, though.

Afternoon showers and storms will increase slightly for Saturday, then increase a bit more for Sunday. Even still, there will probably be some unfortunate locations that get missed by rain all three days.

Temperatures will warm a few more degrees this weekend with highs Saturday and Sunday reaching about 90 degrees. Some areas will end up warmer than this, while the typically cooler higher elevations will probably fail to reach 90.

Dewpoints through the weekend should stay in the 60s, so we should avoid the super humid air. This will also keep our overnight temperatures in the 60s, providing at least some nighttime relief from the daytime heat.

There may be more widespread showers and storms on Monday as a low pressure system passes through. Temperatures behind that system will return closer to normal with some additional rain chances through next week.
