Taking a look at the rest of this month (keep in mind, this is based on computer models that have been wildly inaccurate so far this winter)...what's in store for the next 2 weeks:

1) The current cold air mass sticks around long enough for us to get in one decent snow tomorrow - 1-3" in most spots with isolated areas of 3-5". The most recent model runs are showing a little more moisture available so it might end up more like 2-4" for most.
2) After Monday's snow the temperatures moderate back to normal (for this time of year) with highs in the mid to upper 40s for a week or so.
3) Around the 20th-25th, the models show a brief warmup into the 50s, possibly even touching 60 before the next arctic shot current scheduled for the 25th, temps will dip back into the 30s.
4) GFS is showing a monster cutter-type storm around the 25th originating in the northwest, heading south into Texas and then roaring northeast through the Ohio valley. Take it with a grain of salt - GFS is highly inaccurate on storms that far out.

So, in summary, we've got our current shot of winter with the cold and snow tomorrow, things moderate back to normal temperature-wise until the last week of February, then a bump and dive with temps topping out possibly around 60 and the bottom drops out around the 25th, with the slight possibility of a big storm around that time. Whatever the temperature trends become, the pattern is definitely changing to an active one. So between Monday's snow and the possible storm and cold air later in the month, we've got two shots at Snow/Ice for the rest of February. Then we're on to the last few weeks of meterological winter. What March has in store for us is anybody's guess at this point but I'd put money on a rough couple of weeks at the beginning of the month, with at least one last big shot of cold air and a chance at some snow, followed by a round or two of severe weather and warming temps.

We'll see!

Well, what do you know...those GFS model runs from a couple weeks back that forecasted a major arctic outbreak into the CONUS around February 3-6th - might have been right after all (if off by a week anyway).The next week will see a major shift to cold and stormy that has been hard to find all winter long this year. Temps in the midwest will dip from the 30s, 40s and 50s into the 10s and 20s, with the possibility of an accumulating snow/ice event here in the STL met...

GFS no longer forecasts any kind of extended cold air outbreak over the northern half of the US for the next couple weeks.With that said, clearly GFS has been utterly useless in making predictions any further out than 5-6 days all winter long.Ugh, this winter has been one of tough forecasting, imminent pattern changes followed by reversals, and stagnation. If we don't get a decent cold air outbreak (it was 65 today in Illinois where I live) in the next 2 weeks then ...

LinkGFS is still calling for a hit of arctic air to punch into the midwest, although the latest run has it coming in a couple days later and going slightly more east and to a lesser extent to the south than previous runs in the last week. While this will bring some extremely cold air into the midwest for a couple days, it appears it won't stick around long, as temperatures appear to rebound back to normal or slightly above normal by the 7th. We just can't seem to br...

LinkStarting to see more agreement with the newer GFS models for a major arctic outbreak in the midwest the first week of February. This morning's run has the cold punching even further south than before, with temperatures Feb 2nd-3rd here in Illinois dipping into the single digits. We'll see how the models trend the next week or so.
