The combination of some very light winds and the ever present marine influence early Friday morning has led to the formation of patchy fog. With the wind out of the south expected to pick up during midday, any low visibility issues, while isolated, should disappear.
Temperatures will climb well into the 70s Friday afternoon and all should be much higher than they were Thursday. Also, the winds could gust as high as 35 miles per hour by day’s end.
The next feature we will be watching closely is a cold front, which is going to bring a few showers and a heavier thunderstorm or two — first in areas north and west of the city after 5 p.m. and then across much of the Greater Baltimore Area on Friday night (especially early, or before midnight).
A general 0.50″ to 1.00″ of rain is expected, although some of the harder downpours/pockets of heavier rain could generate even more than an inch. The front is going to be ushering in some much cooler air very late Friday night and Saturday morning, so even though the eventual loss of energy Friday night (due to a lack of heating) and also the strong marine influence should curtail any possibility of severe thunderstorms, the bout with rain that we’re expecting could still result in some minor flooding problems.
Saturday, all rain should come to an end very early, leaving behind some clouds and a cool, gusty wind. Temperatures should be in the lower or middle 60s Saturday afternoon.
Clearing should occur either late Saturday or early Saturday night, and then Sunday will be a fairly sunny, but cooler day. Most temperatures will fail to get out of the 50s Sunday, and Monday will also be relatively cool with some sunshine followed by increasing clouds.
