The system that brought strong winds to the region last night pulls away from the area today. With the trough axis currently centered over northeast Utah, the area remained under cool, dry northerly flow through the morning. Winds are not nearly as strong at last night, but gust 25-35 MPH were reported in many locations through the morning hours. The strongest winds today have been in the Colorado River Valley, though even there the north winds have been on a downward trend in the past few hours after the strongest gusts topped out around 40 MPH this morning. Winds will continue to diminish through the rest of the afternoon and by 4 PM, gusts will be 25 MPH or less in for most of the region. With the strongest winds and highest risk for wind impacts behind us, let the High Wind Warning in the Colorado River Valley expire. Isolated gusts to 40 MPH are possible here through the early afternoon which could cause impacts on the lakes, otherwise widespread wind impacts are not expected. With no significant systems are expected the rest of the week, so not expecting widespread wind impacts through the weekend Breezy afternoons with gusts 20-30 MPH are possible at times, especially tomorrow and Wednesday in the Colorado River Valley as north winds linger a few more days. Today will be much cooler compared to recent conditions as high temperatures this afternoon are expected to run about 10 degrees below normal. Heights will increase through the week as troughing weakens, which will result in dry conditions and a warming trend. Temperatures will warm each day with high temperatures returning to normal by Wednesday. The warming trend then continues into the weekend, with above normal temperatures Thursday onward climbing a few degrees each day the second half of the week. By the weekend, high temperatures will run 5-8 degrees above normal. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Gusty northeasterly winds (with directional variability between 020-050 true) will continue into this afternoon, with gusts to around 20-25KT expected on at least an intermittent basis.
