An unsettled weather pattern will cause almost daily rain chances this week, but will it amount to much?

An unsettled weather pattern will cause almost daily rain chances this week, but it won't be everywhere and won't amount to much, so don't expect a washout.  Since our region is not in any kind of drought, I consider it nuisance rain because it's not the kind to soak in and help the lawn, garden and reservoirs. Instead, it's the type of rain that's just enough to scare folks inside at times.  It'll mainly just be sprinkles and not much more than that until Friday night into early Saturday.  At that point, a cold front should cause a good soaking before plenty of sunshine and cooler temperatures into the weekend.

Here's Monday morning's 7 day forecast, and notice the numerous slight chances of rain.




However, look at NOAA's Quantitative Precipitation Forecast (QPF) from the Weather Prediction Center through Thursday morning as it indicates only 0.01" to 0.10" of rain possible in the D.C. metro area.

A strong cold front should hit Friday night, and this should bring more substantial and soaking rain.  Preliminarily, I'd say approximately 0.33" and 0.75" possible at that point.  It also looks like this front will drop high temperatures into the mid 60s for the weekend with sunshine.

No drought according to the U.S. Drought Monitor:
