We have entered about a week or so period when there won’t be much of a dynamic weather pattern affecting us. First, we have the cooler air behind the front, which will keep highs in the 70s to low 80s the next couple of days. Easterly winds off the ocean will keep the air a little damp, holding lows at night in the upper 50s and low 60s in most places, but no rain is expected through at least Sunday, excluding maybe a few afternoon pop-up showers west of Interstate 77. Early next week, a shift of wind to the southwest aloft and at the surface will bring in hotter air for a few days, with highs shifting more toward the 90-degree mark, perhaps even higher for some locations a day or two. Humidity will build too, but there will be little to trigger it — maybe a weak upper-low passing through Monday, but other than that, just typical summer afternoon pop-up showers and storms related to daytime heating and terrain influences.
Lest you think we’re going to just roll into a long, hot, dry summer out of this coming pattern, there is strong reason to believe it may not last. Indications are strong on many long-range models that the dominant high pressure — the “heat dome” as we sometimes call it — will set up in the West. The Climate Prediction Center’s 6-10-day temperature map bears this out well. When high pressure builds in the West, we end up on the downhill side of it, so to speak, with northwest wind flow around the high’s clockwise circulation pushing cold fronts into our region. Coupled with the moisture that will be building up next week, that could mean more periods of rain and storms — the CPC’s 6-10-day precipitation map shows this, as we are in the darkest of greens on the map. So by late next week, it is quite possible based on forecast trends that we will return to a showery/stormy pattern that is not searing hot, after a few stagnant more summerlike days to begin the week.
