Weather: The Classic Definite MaybeBy Greg Lawson
STAFF METEOROLOGIST -- Forecasts like today’s remind one why forecasters often like to talk in terms of percent chances of precipitation rather than just saying whether it will or will not actually rain or snow. Appealing to that convention, I give it better than a 70 percent chance of rain and mixed precipitation today, but it is certainly not clear cut.
A low pressure system is approaching us from the Ohio Valley. It will track primarily in accordance with the upper-level steering currents. Errors on the order of tens of miles could mean the difference between being wet and dry. We could even experience intermittent rain depending on the fine-scale storm organization. Regardless, it is clear that whatever rain we do get will be light, and that it and its associated clouds should clear out by late evening.
Following the low, we’ll be under the clear and cool shield of a high through the weekend with temperatures just above freezing during the day. The high will clear out by Monday morning and the low which replaces it may bring more precipitation if tracks far enough north.
Today: Gray and mild. 70 percent chance of rain possibly mixed with
snow. Light variable winds. Clouds and precipitation will clear by
evening. High of 45°F (7°C).
Tonight: Clearing up. Wind speeds increase and become northwesterly.
Low of 23°F (-5°C).
Saturday: Scattered clouds. Persistent northwesterly winds. A chilly
high of only 33°F (1°C). Low of 20°F (-7°C).
Sunday: Partly cloudy. Similar to Saturday. High of 34°F (1°C). Low in
mid to low 20s (-6° to -4°C).
Monday and beyond: Temperatures rising slightly with possible rain.
