Average high temperatures at this time of year in Baltimore are in the low 70s, and we're running in the low 50s so far today, with little hope for getting much warmer.
Add to that a pretty healthy dose of rain overnight and into Monday morning, and you get a soggy and dreary day in Charm City. BWI-Marshall Airport has reported more than three-quarters of an inch of rain since it began Sunday evening. We have 0.62 inch on the gauge here at The Sun.
(The data didn't make it to the WeatherUnderground website because somebody turned off my computer early Sunday morning, thank you very much, even though THERE IS A SIGN OVER THE BUTTON THAT SAYS "DO NOT TURN OFF!") There. I feel better now...
The moderate rainfall we saw early today should be easing up from here on, with lighter rain and drizzle expected across the region into the afternoon. Drier air could also creep in from the south and west, providing a few breaks in the clouds.
The crummy weather is the result of several factors. There's a coastal low spinning just off Delmarva, and an upper-level low spinning over the Ohio Valley. Neither has much pushing it to move along. So, they remain parked pretty much where they are, dragging cold air and moisture off the Atlantic and swinging it our way out of the north, and making us cold and wet.
So, the risk of rain will remain in the forecast for a another two days, until high pressure arrives to shove the whole mess off to the northeast, if the forecast holds up. That would be Thursday, when forecasters out in Sterling say mostly sunny skies will return for the weekend, and daytime temperatures should climb back to 70 and higher - pretty much where they should be in early October.
