April Rain Tally Climbs Higher

Were this February, today would have tied for the wettest day of the month.

Alas, it’s April, and a much higher standard for sogginess has been set.

While it was intense at times, the 0.37 inches of precipitation that fell this morning at Sea-Tac was a far cry from the record-smashing 1.54 inches that deluged the city on Sunday. Still, it was a decent enough chunk of change to lift this April’s rainfall total to exactly three and a half inches—leaps and bounds above the norm of 2.71.

With additional wet weather coming down the pike, we’ll add to this number even more over the next few days, but first, it’s time to dry out.

The cold front that caused all the ruckus this morning has already moved into the Cascades, ending the showers for most places along the I-5 corridor. One notable exception is along the King-Snohomish county line, where rain is still falling thanks to the Puget Sound Convergence Zone. Showers should wrap up there shortly as the Zone fizzles and heads further east.

A fair amount of sunshine is likely the rest of the afternoon from Seattle south, allowing temperatures to rise a few degrees into the upper 50s—right about normal for this time of year. With continued clearing overnight, lows will be much cooler, dipping to near 40 degrees.

We cloud up once more tomorrow, with a few pop-up showers wandering around the Sound, but most of the day will be dry. High temperatures will max out on the cool side, only making it into the lower 50s.

Friday kicks off on a mostly clear note, but with a cold front approaching, we’ll be socked in by mid-day. The moisture arrives in Western Washington during the late afternoon hours, with lighter amounts falling in the Seattle area due to the Olympic rain shadow.

Rain picks up in the city early Saturday as a Convergence Zone slides through, with a drying trend by early afternoon. However, the region will be in the vicinity of a cold upper level low by then, limiting highs to near 50 degrees.

The cool, generally dry weather continues into Sunday, with temperatures topping out nearly 10 degrees below normal in Seattle. From a glass-half-full perspective, we’ll least be warmer than last Sunday—when the mercury only hit 47—and a zillion times drier.

You’ve got to start somewhere, right?
