.Forecast Summary...Well above normal temperatures and gusty winds are being observed this afternoon. The lower elevations in Area 25 are particularly warm with mid to upper 70's occurring. Today will likely be the warmest day of the week. The area of high pressure that's responsible will weaken over the next several days. As it does so, high temperatures will gradually cool and northeast winds will diminish. The high will not completely dissipate and remain over the region through mid next week. This will keep our area dry with highs closer to normal. Looking ahead to the end of next week, there are indications of a pattern shift. Clouds and wind will be on the increase. There's a fair amount of uncertainty as far as precipitation goes.
