We’re pushing 6 days now since our last measurable precipitation and that unusually calm, boring stretch of weather will continue for a couple more days. Despite some low clouds at times, expect our quiet and unseasonably mild weather pattern to continue. A late week frontal passage (FROPA) will pull a true taste of spring north into the Ohio Valley and lower Great Lakes Thursday into Friday. We still don’t anticipate this being a significant precipitation maker for central Indiana.
A secondary (much stronger) low pressure system will ride along this pressing boundary and impact areas to our east (and south) with heavier precipitation over the weekend into early next week. The southern Appalachians once again may “cash in” on a hefty snow event.
This more active period comes as a wholesale pattern change gets underway with a significantly colder air mass aimed to overwhelm much of the Lower 48 as we push into next week.
We note longer range models showing cross polar flow setting up late February. To no surprise, the ante is upped for the threat of a period of significant cold prior to month’s end.
We’ll watch for the threat of new winter weather opportunities to emerge during this colder pattern down the road.
