BLOG: Improvement On The Way
Adding some night and morning fog to next few time periods due to high moisture content of atmosphere and relatively light wind. Otherwise, there's still a vigorous upper-level low pressure system, which will be spinning its way across the central Appalachians today and towards the mid-Atlantic coast.
While it is rather cloudy this morning, we anticipate some breaks in the cloud cover today, which will cause greater insolation (solar heating), and it will also push most temperatures into the mid and upper-70s this afternoon. And, with that pool of colder-than-normal air aloft still located over the mid-Atlantic states, we're concerned that another round of thunderstorms will develop today. These will be capable of producing some strong, damaging wind gusts, hail and more downpours. While none of these are particularly appealing, the third in that series could prove to be the most threatening, because torrential rains occurring on already saturated ground will aggravate recent flooding. A Flash Flood Watch has been posted for the Greater Baltimore Area, which will be starting at 10 a.m. and runs through this evening.
We're going to continue to drive home the point that while today's rainfall coverage (and intensity) shouldn't be as widespread as yesterday's, and tomorrow should offer a little less than today, there are still going to be pockets of convection and instability generating by the heating of the daytime, which will still result in a couple of showers and a thunderstorm. We still want to be cautious about Saturday. It should be dry for the Preakness, as long as that upper-level low continues to weaken. Then by Sunday, the upper-level low pressure system should be weak enough, and also far enough to the EAST of the area, that it'll no longer threaten to bring a shower or thunderstorm to the area.
The leading edge of some much warmer air arriving early next week still looks as if it could bring a couple of showers and a thunderstorm to the area on Monday. We're not sure if Tuesday should also be included in this category. But, given the wet pattern we've been dealing with, we wouldn't bet against it!!! Have a good day.
