.SHORT TERM...(This evening through Sunday night)
Issued at 1258 PM MDT Sat Jun 12 2021

A strong upper ridge will build across the Rockies over the next
24 hours. 80 decameters rises are expected at 500 millibars 
between today and Sunday. 700 millibar temperatures are progged to
range between 10 Celsius north to 15 Celsius at 00Z Sunday 
increasing to 14C north and 19C south by 00Z Monday. Models show 
a weak wave pulling across eastern Idaho Sunday afternoon and 
evening, but the building ridge, limited moisture and subsidence 
from the ridge should prevent any convection. Thus no 
precipitation through the short-term with unseasonable hot 
temperatures with Sunday being a few degrees warmer than what 
occurs this afternoon. 

.LONG TERM...(Monday through Saturday)
Issued at 1258 PM MDT Sat Jun 12 2021

The Four-Corners High will be set up nicely on Monday, persisting 
through at least Wednesday. Models are still very confident in the 
behavior of the high through mid week. The ridge is looking to 
flatten a little sooner than previously predicted, late on 
Wednesday. As a result, temperatures look to be a little cooler now 
on Wednesday across the region. We are keeping the PoPs through the 
long term period on the dry side for now as the ridge will continue 
to suppress any activity.

The strength of the high starting Monday is still above 5800 meters, 
and the high temperatures will be in the 90s across much of the 
region. Locations east of the Divide will hit 100 or better on 
Monday and Tuesday. Record highs are very likely for the first half 
of the work week. Relative humidity will also stay in the teens to 
single digits for fire weather concerns, although winds are still 
progged to stay on the lighter side all week.

Thursday to Saturday will see the high slide south and a more 
westerly flow setting up over the forecast area. This will bing the 
temperatures down a bit, although still well above normal. There 
will be a chance for some very isolated convective activity by the 
end of the week, but still not looking too impressive.

.AVIATION...(For the 00Z TAFS through 00Z Monday)
Issued at 500 PM MDT Sat Jun 12 2021

VFR conditions will prevail through the forecast period. Lightly 
gusting winds at KBPI, KLND KCPR, KJAC and KRKS will diminish after 
02Z. Winds and weather through Sunday will be light and dry.

.FIRE WEATHER...
Issued AT 1258 PM MDT Sat Jun 12 2021

Hot and dry across all fire zones through at least the next couple 
of days. Overnight humidity recovery will be poor to moderate. High 
temperatures will be a bit warmer Sunday than today. Critically low 
afternoon humidity is expected over much of the area Sunday, but 
winds are not expected to reach critical fire weather thresholds. 
Smoke dispersal on Sunday are expected to be very good to excellent 
over the west and south, to good over the rest of the area.
