...REMAINING DRY WITH A WARMING THROUGH MIDWEEK;
THUNDERSTORMS POSSIBLE BEGINNING WEDNESDAY...
.BROADCAST DISCUSSION...A warming trend will continue today,
as the region remains under a weakening northerly flow. High
pressure will then build overhead through Wednesday, allowing
for hot temperatures and very low RH. Moisture will slowly
spread into the region beginning late Wednesday, with an
increase in thunderstorm chances later this week.
.DISCUSSION...High pressure centered near the Pacific Coast
is maintaining a dry northerly flow downstream across Utah.
As the airmass slowly modifies, temperatures will trend a
little warmer again today while the airmass remains very
dry. Although the winds will trend a little lighter today,
this northerly flow combined with a warm and dry airmass
will elevate fire weather conditions, particularly across
southern Utah east of I-15.
The upstream high will move overhead Tuesday, resulting in a
continued warming trend which will persist through Wednesday.
With this hot, dry and increasingly unstable airmass in place,
afternoon RH will fall below 15% across all elevations of
central and southern Utah, and northern Utah below 9000 feet.
This will be followed by a night of poor recovery Tuesday
night across most locations south of I-80.
By late Wednesday, moisture entraining into this high will
begin spreading into the area, resulting in a slight chance
of late afternoon high-based showers and dry Thunderstorms
mainly over the terrain. Moisture will continue to slowly
increase through Thursday, resulting in a better chance for
predominantly dry thunderstorms across much of the state.
This moisture looks to remain in place through at least
Friday maintaining a chance for showers and thunderstorms.
The chance for wetting rains will increase by Friday,
particularly across central and southern Utah. With the
increase in moisture, daytime RH will trend higher during
the latter portion of the week with improved overnight
recovery.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
