   Concerning...Severe Thunderstorm Watch 420...

   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.
