Today was a standard February day, cold and partly cloudy. High temperatures barely scraped into the 40s and will drop overnight. However, high altitude clouds begin to move in at the beginning of the night, signaling the approaching snowstorm.<\/p>\n

Tonight:<\/strong><\/p>\n

Temperatures drop below freezing overnight, falling into the upper-20s. Clouds continue to accumulate overnight as the storm approaches.<\/p>\n

As temperatures fluctuate around freezing in the early afternoon, the snowfall will transition into a wintry mix, composed primarily of sleet. Cold ground temperatures could lead to ice forming, especially in the case of melted and re-frozen snow.<\/p>\n

Snowfall in the early morning transitions to mixed precipitation in the early afternoon, which is then followed up by rain (HRRR model on Tropical Tidbits<\/a>)<\/p><\/div>\n

After a couple of hours of wintry mix, temperatures warm up enough to transition into rain. At this point, temperatures should be warm enough to start causing snow and ice to melt, but cold ground temperatures could leave some ice.<\/p>\n

Tomorrow Night:<\/strong><\/p>\n

The warm sector continues to move in overnight, bringing with it more rain and higher temperatures. Overnight and daytime warming should cause considerable melting of ice and snow, mostly clearing up the effects of this storm for Thursday.<\/p>\n
