11/9 – Brittany’s “Cooling Trend Has Begun” Wednesday Evening Forecast
After record heat the past few days, more fall-like weather is underway today across the area as a drier air mass is advected in from the east around the southern periphery of a large surface high sprawled over the eastern CONUS.
Upper-level cloud cover is increasing over the area today in association with the outflow of Tropical Storm Nicole situated over the northwestern Bahamas which is expected to pass over the Florida Peninsula and track well east of our area. The primary impacts from this system will come from increased cloud cover and elevated daytime winds out of the east associated with the strong pressure gradient built between Nicole and the strong surface high to thenorth. These factors will be an impediment to more efficient diurnal heating/cooling of the surface despite the drier air mass present. Additionally, with the presence of this drier air mass ahead of Nicole, no precipitation is anticipated in association with Nicole as it turns northward over the southeastern CONUS on Friday. Rather, the better chance of rain will come on Friday night into Saturday morning as a strong cold front approaches the area.Timing of the front has lagged a tad in latest guidance and the current forecast reflects the front arriving after peak cooling hours on Saturday.
