WEATHER BLOG: Sunday

For the day today, high pressure will slide east off the coast, allowing for a westerly flow to return to the region by this afternoon. We will also be watching an area of low pressure well to our southeast that could take on some tropical characteristics (National Hurricane Center outlooks this feature as 10% development, so not a large chance of this happening). This may lead to a shower or storm on the Eastern Shore, but otherwise it will be a nice day around the region.

By Sunday night into Monday, an upper level and accompanied surface low will intensify across the midwest, dragging a cold front across that region. By Monday morning, guidance is pointing toward the front being located pretty close to Pittsburgh and advancing slowly eastward. Ahead of it around our region, it will get briefly more humid Monday with temperatures into the upper 80s to near 90. One note is that guidance has trended slower with this front, so we removed precipitation from the forecast during the day Monday. It looks like weakening showers and thunderstorms will invade western portions of the viewing area around sunset, advancing eastward overnight. This front should also push whatever low that is to our southeast, out to sea.

On Tuesday, as is typical this time of year, the front will slow significantly and nearly stall along the coastal plain. As of now, it appears any showers and thunderstorms should cease late Monday night, leaving Tuesday dry across our region. It is probably worth mentioning there could be a leftover morning shower especially east of BWI. Humidity will also come down Tuesday afternoon with highs in the middle 80s. Wednesday looks wonderful and pleasant with temps also in the 80s. The upper low will hang around the eastern Great Lakes through the end of the week, so after Wednesday, We will likely see some puffy afternoon cumulus for the end of the week.

Surface high pressure truly builds in for Friday and into the beginning of next weekend with warming temperatures overall. Late next weekend into the 7-10+ day range could potentially be quite warm for late August and early September- stay tuned!
