We're done...

I was going to do a more detailed and technical update showing what I had hoped was the small amount of remaining potential for the mid week system. However after the latest model reviews, it would just be an effort in futility and losing some sleep. Yes, I am bitter and there is no hiding it. Too often the models show potential and then take it away.

In general, the warm air is coming in and making a wreck of everything. Right now the temperatures at 850mb (5000 ft.) range from -10 t0 -13 Celsius. By Monday, they have risen to about -5 Celsius and continue the climb. When the storm is going, we are several degrees above freezing at 5000 ft.

Surface temperatures which have been cold also rise to middle 30's. Combining the two results in a cold and miserable rain. Of course after most of the system has passed, the surface and 850mb temperatures fall possibly producing a couple of inches at best on the back end. Otherwise the storm will be a bust for our area.

If we do get a big snow producer from this storm, then the models will need to be wrong and the storm's low pressure would need to dig deeper south before ejecting northeast. That will (need to) happen on Tuesday. I will follow the low track to see how it verifies.

Monday Morning Alert: While the focus has been on bigger mid week storm, there is a smaller system moving through late Sunday evening into Monday. It should being us a nominal amount of snow of an inch or less. Like was thought last week, the snow will fall early morning and through the rush hour. Expect possible hazardous and wild driving conditions on Monday morning with people relearning how to drive on snow covered roads. School delays are possible.
