A blast of arctic cold is expected to sweep across the Tennessee Valley on Tuesday, bringing with it a chance of snow.
The front comes after a day of milder temperatures — a high in the mid-50s — on Monday, according to Times Free Press news partner WRCB.
While the Chattanooga area will be on the edge of Tuesday's front, it'll still be the coldest temperatures the area has seen so far this season, WRCB reports, with the low dipping down to 10 degrees and the high only climbing to 39.
Morning rain is forecast to briefly turn into sleet by Tuesday afternoon and then into snow, according to WRCB. Some of it may accumulate in certain areas, especially in higher elevations.
Wednesday won't be any warmer, either, despite a mostly sunny forecast. Wednesday's low is expected to be in the low teens and the high in the low 30s, barely above freezing.
Temperatures are expected to warm back up slightly on Thursday, with a high in the low 40s and a low in the mid-20s, but a wintry mix is likely again on Friday, though not as cold as Tuesday.
Hamilton County Schools spokesman Tim Hensley said the district will be closely monitoring the weather as officials "talk about it all day Monday" and decide whether to close the schools.
The earliest a decision will be announced is Monday afternoon, he said.
"We like to [make the announcement] at least a day before," he said. "We'll just have to continue tracking and see how it goes."
So far, students have missed only two days due to weather, Hensley said. The district has eight school closing days built into its calendar.
"[We're] still in good shape," he said, with six more days available before officials have to start looking at scheduling make-up days.
The record low temperature for Jan. 29 in Chattanooga was 1 degree, recorded in 1966, while the record high came in at 73 degrees in 1932. The average temperature for Chattanooga this time of year is 41 degrees.
