Roller Coaster Continues

As is typical for Fall and Spring, the large weather swings will continue for the foreseeable future. Currently temperatures are moderating from the most recent arctic air invasion. Temperatures this weekend will warm everyday possibly reaching the mid to upper 60's by Sunday. A quickly deepening low pressure system and strong cold front will bring rain and potentially severe thunderstorms Sunday evening. The front will move through early Monday morning sending temperatures crashing into the upper 30's by evening. Currently the trough is not looking as deep as earlier predicted so this shot of arctic air does not appear to be as extreme as what we experienced on the 12th of this month. Temperatures will moderate starting Wednesday and continue until the next front approaches late in the week.

The flow will become  more southerly on Saturday propelling temperatures into the mid and upper 50's as the western storm system approaches the Plains. 

The western system will quickly deepen as it approaches the western Great Lakes on Sunday bringing more warmth and moisture into the Ohio Valley. Strong southerly winds will bring temperatures into the 60's across much of the area.

The combination of warmth, moisture, upper level support and a strong low pressure system will provide an environment conducive for severe thunderstorms. These storms will be capable of producing strong winds and if enough sunshine breaks through to destabilize the atmosphere, tornadoes. Please stay alert to this potentially dangerous weather situation.

Both the ECMWF and GFS  indicate a shot of arctic air arriving on Monday possibly producing some lake-effect snow in northeast Ohio Monday night. Temperatures should not rise above 40 on Tuesday. 

Wednesday this cold air will move off to the east with temperatures moderating back into the 40's.
