This week is setting up to look a whole lot like last week as far as when we'll see rain and (eventually) sunshine. What you see out your window is what you get for the next couple of days, although the heavy rain and (possible) thunderstorms will give way to more showery events Tuesday and Wednesday.

But by Thursday, like last week, we will break into a warmer and drier pattern, with highs crowding 80 degrees by Saturday. The weekend, at least from this distance, looks much like this past weekend, which was terrific.

So far, here at Calvert & Centre streets, we have clocked in more than 0.6 inch of rain since it began around 7 a.m. Rain rates have topped 0.4 inch an hour at times. I'd link you to our station, but our data logger remains off line.

The airport has reported about the same amount. Add that to the total for April so far, and we're looking at just over 4.6 inches for the month to date. A "normal" April (the average for the 30-year period from 1971 to 2000) produces 3 inches of rain. Surprisingly, April is, on average, Baltimore's driest month. This time, it is the wettest month here since September 2008, which dropped 7.72 inches at BWI.

We could get as much as another three-quarters of an inch out of this storm before the low drifts off to the east. If thunderstorms develop as a warm front lifts through the region this afternoon, there is also the possibility of large hail and damaging winds, forecasters say. Keep a weather eye out between 3 and 9 p.m.

Then there's yet another low due in on Tuesday, with more showers along the associated cold front. Showers may linger into Wednesday before skies begin to clear out. 

In the meantime, we remain unseasonably cool, with highs today about 10 degrees below the long-term average for BWI at this time of year. By Friday, we'll be in sunshine again, and temperatures will rise well into the 70s, with weekend temperatures 5 to 10 degrees above the averages. Nice.
