Valid 011700Z - 021200Z


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/

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

...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.
