:: Weekend of Wetness?
All in all, this summer has been bar-none the best of my memory, weather wise. Temps have been seasonal or better - always. Sunshine has been plentiful. For the first half of the summer, precip was on the borderline of "just enough" and "not enough". July was alltogether too dry, and now it looks as if August may be attempting a rebound.
Previously discussed system now working its way across the Rockies. Upper flow in zonal mode will carry it over the front ranges as lower level flow becomes monsoonal from the desert SW, aided by a relatively concentrated H5 high centered over TX. Warm frontal boundary will set up as theta-E and upglide of the monsoonal flow carries NE-ward into MN today. Front will genesis in central MN this afternoon, and will be the first focus of convection for northern MN areas this evening as folks head up to cabins on the 4th-to-last weekend of summer.
Low pressure center will sweep through SK and aid propogation of the cold front to a very familiar orientation -- the system will be positively tilted like the early week system that dumped 3-5" over much of central and southern MN. This means folks from Hinkley to Marshall and points east will get wet, but not until Saturday evening...enough ingredients in the NAM/ETA model to prove the need for severe chances (cape and impressive theta-E and vort maxes align ahead and paralell to the front by 00Z Sunday). NAM also paints some impressive precip max "bullseyes" over the same areas. Folks that saw the heaviest rains earlier this week may suffer deja vu on Saturday.
TODAY...Partly Cloudy, High 87. Humidity on the increase, so it will feel hotter...SSE winds 5-10 mph. Low 72
SATURDAY...Partly Cloudy, High 92. Showers and thunderstorms develop in earnest after supper. SE wind 10-15. Chance of rain 70%. Low 65.
SUNDAY...Clear and Sunny. High 84. Low 65.
