Update - February 27, 2015

This is my busiest time of the year doing presentations on severe weather so the frequency of updates will be less.

In the previous post last Friday (click here) I discussed the possibility of heavy snows across Colorado and extending out into the plains.  The following map is the approximate amounts reported across western Kansas.  Keep in mind there was quite a bit of wind so there were bare spots.  Those crop fields with residue or CRP fields caught a lot of it...(click for a larger version).


The immediate attention turns to several upper level storms associated with the jet stream.  The first near the Four Corners will spread snow across much of the area into Saturday.  The second was diving into California.  The possible snow amounts are still uncertain, even this close to the event, because of the sparseness of the upper air sampling.  We really don't have handle on the moisture and temperature profile where the snow will be forming at, until the event starts to unfold.  Computer guidance is all over the place so is of little help.  But, I will throw out an educated guess, and see what happens.  First the satellite image...


and now, the guess...


There could also be sleet or freezing rain across parts of south central and southeast Kansas and northern Oklahoma.  Again, it all depends on the temperature profile as the events unfold.

Beyond this weekend, next week could become pretty active with a strong Arctic cold front headed this way.  The warm air surge may make it well into Kansas which will probably bring low clouds and drizzle (or freezing drizzle until the temperatures warm to above freezing).  Severe thunderstorms might even be a possibility across far southeast Kansas!

At this point any heavy accumulations of snow from that storm will likely be across Colorado.

Good news!  Much warmer weather is expected by next weekend (March 7th).  More on that later when I get a chance to post to this blog (hopefully by mid-week).
