More Snow in Store For This Week

Two weather systems moving in this week will bring precipitation at different times.

Over the past week, many suburban communities picked up between two and four inches with the two pittances of snow that tracked through the region.

Neither system was tremendous in impact, although the second had a bit more bite in its wake as cold air moved into the region. However, this cold shot is not locked in, nor is it loaded up to last long. After Monday, temperatures will return to normal over the duration of the week.That means highs in the 40s and lows a few degrees on either side of the freezing mark.

The normal for this time of the year is a high in the lower 40s and a low in the upper 20s, so this week's weather qualifies for mid-February. Of course, we know how fickle February can be. Four years ago, we flirted with near 70 degree temperatures. Five years ago, we had several inches of sleet and snow in one of the worst sleet storms our region has seen in quite some time. Thankfully, neither of those extremes are on the way; however, two rounds of precipitation are expected in the coming week.

The first will trek through on Valentine's Night – a weak system that will bring a round of scattered rain and/or snow showers. As of post time, it's tough to say whether those showers will be liquid or frozen as temperatures will be close to the freezing mark both at the surface and up aloft. If frozen, some coating accumulations can't be ruled out in a few spots.

The second system of the coming week will arrive on Thursday with mostly rain for our region. The low pressure center with system number two has a bit more pop to it and a bit more moisture, so more widespread precipitation is expected. It won't be a nasty storm but some half-inch rains are possible with it. There's a slight chance this system might start as snow on the very front end in the suburbs but milder air will work in at the surface and aloft, changing any snow over to rain rather quickly. Stay tuned just in case the trend is to go colder with this system and we get a bit more frozen and a bit less rain from it.

The weekend is expected to start off relatively tranquil with seasonable temperatures, with the possibility of another storm system arriving on President's Day, although there is little model agreement on track and timing with that storm.
