Feb 22-10pm Update

Temperatures are currently hovering around freezing and narrow band of precipitation is currently tracking through the area. A shortwave and frontogenesis are helping to enhance the precipitation occurring in the area and thus having likely POPS for precipitation is still justified. Right now, it appears that 1-3" of snow accumulation will still occur before the morning hours tomorrow. Still looking at high pressure and colder temperatures to arrive after shortwave and precipitation tracks through the area tonight.
For Sunday, high pressure, drier air, and colder temperatures will dominate the weather for the day. This intrusion of drier air will help end ongoing precipitation before the wee hours Sunday. The high pressure and drier will allow for decreasing cloudiness during the day except for a some afternoon clouds that may develop during the afternoon hours. Highs will climb into the upper 20's for Sunday. As high pressure and mostly clear skies will dominate the weather Sunday night expect radiational cooling, enhanced by snowpack, and temps to fall rapidly into the upper single digits during the nighttime hours.
For the workweek, the polar vortex will make its presence once again in the upper Great Lakes and this will allow cold arctic air to spill south into the area for this period. Expect highs to remain below normal through the work week. Central Indiana is projected to be on the cusp of this air mass and this will allow the northwest flow to track through the area during this period. This may heighten our chances of seeing Alberta Clippers which could possibly deliver some snow to area before it exits. With that being said will keep pops in the forecast for Monday night-Tuesday as a weak disturbance may deliver some snow showers to the area during this time. Other than that, the rest of week looks dry for now, however, will still watch for the possibility of aforementioned clipper systems to change this prediction.
