Valid 160126Z - 160230Z The severe weather threat for Severe Thunderstorm Watch 420 continues. SUMMARY...Risk of damaging winds increasing with eastward propagating line of severe storms across eastern Montana. DISCUSSION...A line of thunderstorms across eastern Montana has recently shown an increase in lightning activity, cooling cloud tops, and forward propagation speed. A recent report of a measured gust to 79 mph was observed near Fort Peck, MT. This line of storms will progress eastward into more favorable instability and steepening mid-level lapse rates. In addition, surface observations indicate better moisture with dew points in the mid 50s to 60s and temperatures in the low to mid 80s across far eastern Montana. The threat for damaging winds is increasing, with potential for gusts 60-70 mph with some instances of 75+ mph. ..Thornton.. 06/16/2024 ...Please see www.spc.noaa.gov for graphic product...
