Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Salt Lake City Utah
923 PM MDT Thursday Jul 24 2014
Synopsis...a stalled surface front will remain across central
Utah through Friday...maintaining moisture across the south and
drier air across the north. This moisture will slowly work its
way northward during the upcoming weekend...and remain in place
into early next week.
Discussion...a stationary surface front bisects the forecast
area this evening...currently stretching from roughly Delta to
price. To the south moisture remains in place across a good
portion of south central through southeastern and east central
Utah...while to the north much drier air has spread into northern
and west central Utah. Lingering thunderstorm activity remains
isolated...and should end over the next hour or so across the
Uinta Basin along with south central Utah.
Middle level heights are forecast to rise over the next few days as
ridging amplifies across the region. Moisture in place across
southern Utah southward into Arizona will remain in place through
Friday...before spreading slowly northward Saturday through
Sunday. As such the threat for thunderstorms will be on the rise
from south to north during this time.
Made some minor tweaks to the gridded forecast earlier...otherwise
plan to update to remove probability of precipitation once thunderstorm activity dies off.
Aviation...VFR conditions to prevail at kslc through the
overnight hours with north winds switching back to the south
