River Update Summer Update

We have been so fortunate the way things have played out from the drought killing winter to the cool spring limiting the snow melt.  Speaking of cool springs check this picture off the webcam at Yellowstone this morning.

The tail end of cold front responsible for this is headed this way, but there will only be very minor impacts in the form of slightly below average lows temps. Monday we could see some more pop up showers returning and later in the week as well. This time of year the short term and intermediate models really struggle, which is why you don’t see too many forecasts this time of year from me.

Rivers Update

So most of the rivers in the area will be at just below flood stage and will naturally peak over the next 24-72 hours.  I always get questions about the historic 1911 flood this time of year. There is a huge difference between now and then, that flood occurred in October when the remnants of a tropical storm set up over the San Juans. So there is absolutely no way to compare the two. Interestingly enough the 1910-1911 Winter was average for snowfall with 67″ downtown, although 57 of the 67 inches all fell in February.

These forecasts vary daily and if we get a couple spots with heavy showers in the next couple of days it will obviously affect the flow.

Once again here is the explanatory text for what 7 feet etc mean.

To illustrate how much a persistent stalled storm can impact river flow, this happened in Texas a couple of days ago.

Summer Update

Meteorological Summer started 7 days ago and in most areas, it is playing the part pretty well. The rest of June looks to be near normal to slightly below normal temperatures and believe it or not below normal precipitation, this is according to the new Euro 46 day run, it would surprise me if that happens, but if we are below normal for precip in June remember June is the driest month of the year for us. As we slide into July at the moment, it looks like we will transition to slightly above normal temperatures.

I also get asked a lot about Monsoon Season. All I can say about it, for now, is Monsoon=Not Soon. I expect a late start or a “Nonsoon” this year.
