BLOG: Dry And Chilly

Not much to discuss over the next few days thanks to a large area of high pressure overhead. As such, expect a good deal of sunshine today and for the beginning of the upcoming work week, though some high cirrus may appear tomorrow afternoon and evening as a weak upper-level disturbance slides across the region.

It’s not until Wednesday that we even entertain the notion of having a shot at any rainfall, but with a lack of an substantial model support we’ll maintain a dry forecast with a little more cloud cover than previous days. The potential rain maker would be with a warm front which is expected to push northward across the Ohio Valley and possibly extend into the Mid-Atlantic as well, but the eastward extent of the lift associated with the warm advection is in question. Regardless, it appears likely that a storm system will take shape in the lee of the Rockies during the day Wednesday as a moisture laden upper-level low crosses the Southwest.

The newly minted surface low is expected to lift northeastward into the Great Lakes region sometime Thursday. With that the associated warm front will lift northward and into our region Wednesday night or Thursday, so we’ll have to consider rainfall during one or both of these time periods. As the surface low continues northeastward we’ll briefly find ourselves in the warm sector before a cold front arrives Thursday night. We should see some rain with that overnight and perhaps into Friday morning before clearing commences.

Have a great day!
