DAYS 1-5 (JULY 1-5)
Some folks like to start their long weekends on Thursdays, a fair amount start them on Friday, and with Independence Day falling on a Sunday, the holiday will be observed on Monday for many, so we’ll just call this 5-day forecast period the outlook for the holiday weekend. It won’t be a repeat of Memorial Day Weekend, but it is not going to be a stellar period of weather either. The front that moved down into the region yesterday with thunderstorms, breaking our heatwave, sits nearby today and while it dissipates another front will move down from the north and continue to send cooler and less humid air into the region. But less humid is only relative in this case, because the air will actually be quite humid, just have lower dew points, and lower temperatures. We’re going to see a period of showery weather especially tonight into Friday as moisture travels northeastward along these frontal boundaries and upper level low pressure moves into the region. This upper low will take its time exiting during Saturday and Sunday, but the surface air flow which starts out northeasterly on Saturday will turn more westerly by Sunday. This will result in improving weather during those days, but not absent of a little drizzle or a few showers Saturday, and maybe a few pop up showers Sunday. If you want a day to feel like full summer again, that’ll be Monday, when we’re into a westerly air flow and a much warmer air mass arrives.
