PM Update: Quiet before the storm; flood watch Tuesday afternoon and evening

After lots of morning sunshine, the cold air mass overhead percolated enough to create abundant afternoon cloudiness. We also have seen some rain and snow showers across the area. Despite the clouds and showers, highs still rose to within a few degrees of 50, but temps will drop off nicely as the sun sets.

Through Tonight: Any renegade showers (possibly mixed with a few flakes) end around or before sunset, with skies clearing thereafter. We may not get much clearer than partly cloudy though. Temperatures fall to lows in the mid-20s to near 30. Winds slacken a bit, but probably not much, with sustained northwest breezes around 10-15 mph along with higher gusts.

Tomorrow (Thursday): Highs should range mainly from the low-to-mid 40s under lots of sunshine. But, with winds from the northwest around 20 mph (gusts to 40 mph+) added in, much of the day sees wind chills in the 30s. Brrr.

Slow March for tornadoes: March is often the beginning of the uptick in tornado activity heading into the peak during spring and early summer, but it tends to be hit-or-miss compared to later months. Dr. Greg Forbes reports that with only one touchdown so far this month, it’s the quietest start to March since 2002. Last year, we had quite an active March, boosted by the outbreak on the 2nd and 3rd.
