ROCKFORD (WREX) — The Arctic air broke a Valentine's Day record, but the harsh cold doesn't last into the weekend.
Temperatures fell to -10° Friday morning, breaking the coldest low temperature record for February 14th. The previous record was -8°, set in 1916. Wind chills dropped as low as -23° early Friday morning, resulting in frostbite dangers. Temperatures climbed to the low teens by the afternoon, or almost 25° below average.
Conditions keep warming from here. Warmer air sweeps in from the west overnight and through Saturday. Temperatures keep slowly warming after midnight, to the point where we reach the low 20's by sunrise. Highs rise to the low 30's by Saturday afternoon. Southwest winds become breezy, however, so it may feel like the teens to 20's with the wind chill, despite the warmer air.
A few flurries float over the Stateline as the warm air sweeps in. The light snow activity starts up Saturday afternoon. We should see dry skies again by Saturday evening. Less than 1" of snowfall is expected. This may still result in slick spots.
Sunday keeps the warming trend going as we warm into the middle 30's. The end of the weekend stays dry and partly cloudy. We jump into the low 40's by Monday, but that comes with some wet weather. Snow showers kick in during the morning, but transition to rain showers by the afternoon. The snow on the ground may not completely melt away, but we'll see a lot less around the Stateline after Monday.
The warming trend only lasts into Monday. Another plunge in temperature is ahead, but this time its only into the 20's. We'll stay in the middle to low 20's Tuesday through Thursday, with a lot of sunshine. Milder weather and another chance at rain showers looks to be in our long range forecast by next weekend.
