PM Update: More rain to come before a clearer and warmer tomorrow

A day we don’t usually see in meteorological winter (Dec.-Feb) will go down as one of the wettest. In fact, the 1.12” (through 3 p.m.) makes this the rainiest we’ve been since the record breaker of 3.10” on December 7. We have not quite made it to the Leap Day record — well, Dulles and BWI did — of 1.61” in 1892, but there’s still some more water to come before it’s all over.

Through Tonight: Another round of heavy showers and even some thunderstorms is likely as we head through mid-and-late evening (main brunt probably around 6-10 p.m.). This is the same activity which caused tornadoes to the west, though its volatility will diminish while crossing the mountains and entering into cooler air. Additional lighter showers are possible after midnight, but we should generally start clearing into sunrise as lows reach the mid-40s to near 50.

Tomorrow (Thursday): Meteorological spring starts on quite the spring-like note. Skies should be partly to mostly sunny with a moderate wind from the west or northwest around 15 mph with higher gusts. It’s mild too, with temperatures shooting for the mid-60s and some upper 60s possible.

Snow: On the north side of this wet and tornado-laden storm, snow has been falling. It’s been particularly nasty from the Dakotas east through Minnesota and into parts of Michigan. The “Leap Day Blizzard” may ultimately drop up to 1-2 feet of snow across the upper Midwest and into parts of the northeast.

Pollen update: Before the rain, tree pollen was still running high with mold spores low. Tree pollen has been temporarily washed out, but more warmth on the horizon promises more allergy concerns.
