DAYS 1-5 (SEPTEMBER 20-24)<\/p>\n\n\n\n
High pressure will be the dominant force in our weather through Wednesday, and at least into if not all the way through Thursday too. As the high center, which is just to the north of our area now, slides offshore toward midweek, the transition will be from low dew point weather with cool nights and mild days early week to a more humid southerly air flow by midweek. The biggest weather question remains the timing of the next trough and frontal system from the west. At one point, guidance was aiming at Wednesday \/ Thursday for this, and as we’ve gotten a little closer the guidance remains spread on timing with the quickest model bringing the most rainfall through the region Thursday, and the slowest guidance indicating most of the rainfall will occur later Friday through Friday night. For this update, I am making no changes in the timing from yesterday’s post, but don’t be surprised if additional tweaks are going to be needed. For now, just “reserve” late Thursday through Friday as the potential unsettled time period. Rewinding back a bit, a reminder that summer ends and fall arrives with the autumnal equinox at 3:20 p.m. EDT Wednesday September 20, and back a bit more, look for the rise of the full Harvest Moon tonight just after 7 p.m., reaching it’s “peak fullness” at 7:55 p.m. as it sits low in the eastern sky on its rise and will light the landscape brightly all night.<\/p>\n\n\n\n

DAYS 6-10 (SEPTEMBER 25-29)<\/p>\n\n\n\n
The weekend forecast depends highly on the speed of the frontal system moving in late this week and how quickly it departs the region. Leaning toward the potential for early showers September 25 with the departure of that system on the slower side, and late-day showers September 26 with the approach of the next one from the west, with rain-free weather for the bulk of the weekend in between. Still adjustments are likely to be needed. Potentially unsettled weather into September 27 and one more shower threat near the end of the period as we start a cooling trend.<\/p>\n\n\n\n
DAYS 11-15 (SEPTEMBER 30 \u2013 OCTOBER 4)<\/p>\n\n\n\n
More west-to-east flow is expected, with a bit more northwesterly flow possible, which means minor shower threats with passing fronts and an overall cooling trend. With uncertainties in the pattern leading up to this, this is still a low confidence forecast at this time.<\/p>\n","protected":false},"excerpt":{"rendered":"
