Today:

Synopsis of Weather Conditions:

President’s Day 2010 will easily go down as one of the worst days this winter. Snowfall accumulations ranging from 3 to 8 inches have been reported north of the Ohio River with amounts closer to 2 to 6 inches in Henderson and Owensboro (higher amounts were observed towards Owensboro). As you go progressively further south from the Ohio River, amounts becomes less and less as only 2 inches were being reported near Greenville in Muhlenberg County, Kentucky as of 9:45 am CST. Through the remainder of the day, scattered snow showers and squalls will remain a threat with up to an additional inch of accumulation possible yet unlikely. There is a 70% chance of precipitation for your Monday. Due to temperatures falling far below the freezing mark last night as the snow was falling (temperatures ranged from the mid teens to the mid twenties in most areas), the snow has a powdery consistency. With winds whipping up to 30 mph at times all day long, blowing snow will continue to be a problem as well as limited visibilities due to the blowing snow in some of the most extreme circumstances. While temperatures will struggle to rise much off their morning lows in the teens and twenties, wind chills will constantly hover around zero. Expect horrible driving conditions throughout the day with only notable improvement developing on the main roadways.

Forecasted High Temperature

Today’s Wind Forecast: West-northwest winds at 10 to 20 mph with gusts up to 30 mph…

Tonight:

Synopsis of Weather Conditions:

Tonight will be cloudy and brisk as winds continue to howl up to 20 mph at times. While it could be worse (it can only be worse) wind chills throughout the night will easily be in the single digits and, at times, drop below zero. Snow showers and flurries stemming form impulses of energy wrapping around a giant upper level low centered over the Mid-Atlantic (New York, Pennsylvania, etc.) are expected to be scattered across the Tri-state tonight with no accumulations expected. There is a 30% chance of precipitation for Monday night. While the models put the low in the lower 20’s in Evansville, I wouldn’t be surprised if we got as cold as 16 or 17 due to the fresh snowpack and cold flow out of the west-northwest. None-the-less, cloudy skies and an aggressive surface flow helping to mix milder air down to the surface will help to counteract the chilling effects of the snow.

Forecasted Low Temperature

Tonight’s Wind Forecast: West-northwest winds at 5 to 15 mph with gusts up to 20 mph…


Tomorrow:

Synopsis of Weather Conditions:

Tomorrow will be another rough winter day as Old Man Winter continues to throw his weight around (and this year he’s spent a few extra hours at that dinner table). While only a few snow showers are expected as upper level impulses wrap around a larger upper level low centered to our northeast (as described in tonight’s synopsis), the winds will continue to make blowing snow an issue. Little or no accumulations are expected from tomorrow’s snowfall and there’s a 40% chance of precipitation for your Tuesday. To be honest with you, looking at some of the other models, 40% may be too high, and I’ll re-evaluate it for the noon newscast. As for temperatures, we’ll see some recovery, but if we only get to the mid to upper 20’s, we’re still talking about high temperatures that are 15 to 20 degrees below normal. Wind chills during the midday hours Tuesday will be in the single digits and the teens. While temperatures are expected to improve through the workweek (see the Extended Forecast Overview below), they will continue to fall well short of where we should be for February!
