Possible Freezing Rain!
It’s appears as if our general wind flow will closely be driven by a strong NW to SW jet. As this boundary shifts to the NE and then back to the SW we will warm and then conversely cool. With that being said, through the first half of the upcoming week it looks like we’ll get into a weak ridging pattern as the jet moves up to the NE. By the end of the week though, a short wave is likely to bring in a shot of cold air which may coincide with a moist flow from the south at low levels.
Like we saw back in January, this would be a set up for some accumulating ice. A little layer of below freezing air near the surface is all it takes to make things treacherous on the road and plague trees and power lines. Timing-wise a Thursday into Friday event seems to have the most consistency at this point. There has been some agreement in a few of the long range numerical forecasting models and at this point it definitely bears watching. Precipitation appears to be light in association with this scenario but it only takes a little ice to wreak havoc on the roads.
We’ll be monitoring developments in the days to come closely and in the meantime a few days with highs closer to seasonal averages should be nice!
