   ...CRITICAL FIRE WEATHER AREA FOR PARTS OF EASTERN NEVADA INTO
   WESTERN UTAH...

   The previous forecast remains largely on track. Current visible
   satellite depicts partly cloudy conditions across the Northeast,
   with RH dropping below 40% amidst surface northwesterly winds
   increasing above 10 mph in several locales along the New England
   coastline. Continued boundary layer heating suggests that elevated
   conditions will occur through the afternoon hours across parts of
   New England. A very slight westward expansion of the critical area
   was also made based on the latest model guidance. 

   Please see the previous forecast below for more details.

   .PREV DISCUSSION... /ISSUED 0109 AM CDT Mon Jun 01 2020/

   ...Synopsis...
   Upper-level troughing will continue over the West Coast with an
   upper low beginning to become cutoff off Baja/southern California.
   An upper ridge over the central CONUS will flatten as multiple
   mid-level shortwave troughs traverse along its northern periphery. A
   surface pressure trough will extend out of the Lower Colorado River
   Valley and into the eastern Great Basin.

   ...Great Basin and Four Corners...
   Critical conditions are expected across eastern Nevada and western
   Utah today as south-southwest sustained surface winds of 15-25 mph
   develop amid minimum RH of 8-15%. Elevated conditions are expected
   across central Nevada into northern Arizona and northward through
   eastern Utah and northwest Colorado. Of particular concern are these
   elevated/critical conditions developing after recent lightning
   across much of the delineated area. Locally critical winds/RH are
   likely across portions of southern Wyoming today, however, fuel
   conditions will mitigate the threat. 

   Thunderstorms are expected to develop across portions of the Four
   Corners and Colorado Rockies today. However, storm motions will be
   slower than in days past and this will be multiple consecutive days
   of thunderstorms, likely leading to increased values of fuel
   moisture. 

   ...Northeast and New England...
   Elevated conditions are likely to develop across portions of New
   Jersey, southern New York and into southern/eastern New England.
   Northwesterly winds of 10-20 mph and minimum RH of 25-35% are likely
   to develop by mid-day and continue through the afternoon. The
   elevated area was confined by recent rainfall and where winds will
   be strong enough to meet elevated criteria.
