.SYNOPSIS...A weak system passing through the region on
Wednesday will produce isolated showers and thunderstorms across
northeastern Utah, after which a gradual warming and drying trend
is expected through the remainder of the week.
&&
.SHORT TERM (Through 12Z/6 AM Friday)...Current radar imagery this
afternoon depicts isolated showers ongoing roughly along a line
extending northeastward from Wasatch Plateau to far northeast
Utah. These high-based showers will be capable of producing gusty
outflow winds between 40-50 mph through the remainder of the
afternoon. Otherwise, conditions remain dry across the rest of
the region, with highs near climatological normals.
Benign weather continues into Thursday as the shortwave trough
that created enough instability for weak showers over the past
couple days ejects into the Northern Rockies, allowing more zonal
flow to develop over the region. This pattern will result in
temperatures trending roughly 4-8 degrees warmer across Utah and
southwest Wyoming, translating to highs in the low to mid 90s for
Wasatch Front and most valley locations and near to slightly above
the century mark for lower Washington County.
.LONG TERM (After 12Z/6AM Friday), Issued 235 AM MDT...
Hot and dry conditions will prevail across the forecast area
through the upcoming weekend, as ensemble families remain in
strong agreement slowly building mid level ridging into the Desert
Southwest, with the forecast area within a fairly weak but
predominant zonal flow through the weekend.
By early next week ensemble guidance continues to be in strong
agreement developing a weak trough along the Pacific Coast, which
will amplify the mid level ridge downstream across the Interior
West. This will result in a warming trend heading into Monday across
the forecast area, with the Wasatch Front approaching 100F and St
George potentially approaching 110F. Not much change in long range
model guidance tonight with respect to the evolution of the upper
trough along the California Coast heading toward the middle of next
week, which still looks to potentially allow for a southerly fetch
allowing monsoon moisture to spread northward into at least
southern portions of the forecast area as early as Tuesday.
&&
.AVIATION...KSLC...Winds will remain generally northwesterly to
northerly through 03-05Z. Otherwise, VFR conditions will continue.
REST OF UTAH AND SOUTHWEST WYOMING...Winds at most sites will be
driven by local diurnal trends. VFR conditions will prevail, with
the exception of KBCE where smoke from nearly wildfires will again
reduce conditions to IFR to LIFR after around 06-08Z.
&&
.FIRE WEATHER...The gradual warming trend continues across the
region this week, with temperatures remaining well above
climatological normals into next week. A gradual drying trend is
also expected statewide, with daytime RH in the single digits to
low teens and worsening overnight humidity recoveries through this
weekend. Despite these dry conditions, there is potential for
high-based showers mainly across the Wasatch Plateau, Uinta Basin,
and into the Uinta Mountains this afternoon. Any showers that
develop will be capable of producing gusty outflow winds to 40-50
mph. Winds remain generally light with typical afternoon breezes
through the weekend, except for Friday as a slight uptick in
southwesterly winds is expected across portions of southern Utah.
This may result in a period of locally elevated to near-critical
fire weather conditions where fuels are critical across southern
Utah on Friday afternoon.
The pattern remains favorable for a push of monsoonal moisture by
Tuesday, with RH trending upward statewide in the days following.
While there is still a bit of uncertainty in the forecast this
far out, it is worth noting the Climate Prediction Center has
placed a majority of central and southern Utah into a Slight Risk
(20-40% chance) for excessive rainfall by the end of next week.
