WEATHER BLOG: Saturday

As high pressure slides eastward off the East Coast today, the flow has become southerly and dewpoints will begin to rise to around 60-64 by day's end. Already some mid and high level clouds in place right now and with mid level moisture streaming in on SW flow aloft, we should have more clouds than sun around throughout the day today. There is no strong force in place today but with warm temperatures and rising dewpoints, there can be a shower or thunderstorm around from time to time today. The best chance will be in the afternoon and probably to the W and NW of Baltimore, though unfortunately the best chance to see something later today in Baltimore could be around the time of the Preakness.

A better chance for showers and storms tonight .... it will be a warm and muggy night as well with temps struggling to drop with lows only in the upper 60s. Another warm and humid day tomorrow with clouds, some sun and temps. soaring into the middle 80s out ahead of a backdoor frontal boundary which will still be well off to the N and NE tomorrow. We may have a little less activity around tomorrow tonight.

Monday highs are well into the 80s again. Warm/humid air mass will still be in place. The chance for a shower and thunderstorm will remain with us as well.

Another chance for a shower/t-storm on Tuesday as low pressure passing well to the north (the same low taking shape this weekend in the Dakotas) will drag a trailing frontal boundary across the region on Tuesday. Behind the front, it will dry out Tuesday night and then for the remainder of the week as well as it turns breezy and cooler with some sunshine and comfortably low humidity.

Temperatures will remain near mid-May normals for Wednesday and Thursday and then a bit above normal by Friday with high pressure in control.
