Things Pretty Much On Track...

Things seem to becoming together for a pretty decent wet Spring storm. The biggest questions that remain are concerning the temperatures. The National Weather Service has continued the Winter Storm Watch this morning for Denver, unwilling to commit to a because of the uncertainty of when it will be cold enough for snow. Castle Rock, and all foothill zones to our west have already been upgraded to a Winter Storm Warning as temperature confidence is higher in these zones.

With models forecasting somewhere between 1.5 and 3 inches of precipitation between tonight and Sunday we can expect at the very least some much needed moisture. The sooner it changes over to snow, the more accumulation we can expect. There is generally about 1 foot of snow per 1 inch of precip - so you can see how significant this storm could be. Will we get three feet if the models predicting 3 inches of precip are correct? ---doubt it. This is because more than likely we will see several hours at minimum of rain before it all changes to snow, and because the ground is so warm that much of the snow that falls is likely to melt!

With the NWS forecasting 10-24 inches of snow for Denver I would expect a winter storm warning to be issued at some point today. They do warn, and I will as well, that some places will remain a rain/snow mix longer.......................... greatly changing total snow accumulations!
