**WINTER WEATHER ADVISORY PARKE-PUTNAM-VERMILLION FROM SATURDAY 7PM EST TO MON 7AM EST**
Saturday night: Rain/snow mix changing to all snow. Low: 32°
Sunday: Rain turning to mostly snow for our Sunday. 1″- 2″ possible, isolated higher totals, beware of slick roads. High: 35°
Weekend Snow Forecast: A winter weather system is set to move into the Valley beginning late Saturday through Sunday evening.
Rain will be possible at first mainly after 5 p.m. EST today for most of the Valley, possibly mixing with snow through the overnight with low temps hovering near freezing, especially in northern portions of the Valley.
By daybreak on Sunday, light accumulations will be possible. Widespread snow will be most likely Sunday morning and afternoon for northern portions of the Valley.
Warmer air has been surging into central and southern portions of the Valley with every model run. Temperatures will climb into the mid to upper 30s on Sunday afternoon and evening. At this point, snowfall looks limited in Terre Haute and southward. It’ll be a mainly rain event with a little snow mixing in early Sunday, and again Sunday night.
There will be a drastic cut-off with snowfall accumulations from north to south. Highest snowfall totals will be north of I-70 in the 3″-5″ range for places like Paris, IL through northern Vermillion, Parke and Putnam counties in Indiana.
The biggest update in the forecast is for areas south. With warmer air set to move into the I-70 corridor, from Effingham through Casey, Terre Haute, Brazil and Bloomington, IN, rain will be the predominant form of precipitation, cutting down on overall snowfall potential. Model average for Terre Haute is right around 0.9″. Snow potential still exists both early Sunday morning before warm air moves in, and again Sunday night when cold air returns. With this set-up, most places along the I-70 can expect snow in the 1-3″ range just north of the interstate, and 1-2″ south for southern Vigo-Clay-Owen, Sullivan, and Greene counties.
It’ll mainly be a rain event in southern portions of the valley, reducing overall accumulation. Southern Martin, Daviess, Knox counties (in Indiana) and southern Lawrence, Richland, Clay counties in Illinois we see snowfall totals staying under 1″.
Extended Forecast: Much colder air arrives on the backside of this system. Morning low temps Monday and Tuesday morning will be near 10° with a high on Monday of only 19. More light snow chances return late Tuesday and Wednesday.
