.SHORT TERM...(This evening through Sunday)
Issued at 300 PM MDT Sat Aug 8 2020

There is a batch of cloudiness associated with a weak upper trough
moving east over the eastern third of the CWA right. There is a
bit of subsidence immediately behind it. Over the foothills and
mountains, there is convective cloudiness developing, but nothing
substantial. On the area radars, there a few echoes hear and
there, but it is likely that very little to rain is hitting the
ground. There was a boundary/cold front pushing south-
southwestward over the northern Metro area earlier, but it appears
to be washing out. It was last discernible on the radar at about
1930Z. It wasn`t much of cooler airmass anyway. Dew points are
still pretty low across much of the CWA; mainly 20s and 30s F for
most areas. The far northeast corner does have some 50s F
currently. Models keep the weak west-southwesterly jet level flow
aloft tonight and Sunday. There is no synoptic scale energy on the
QG Omega fields tonight or Sunday. The low level winds should
adhere to normal diurnal patterns through Sunday. For moisture is
stays dry tonight and Sunday. with precipitable water progs
ranging from 0.25 to about 0.60 inch. For CAPE, there is some over
the far northeast corner of the CWA this evening. On Sunday there
is practically no CAPE progged anywhere in the CWA. There is no
measurable rainfall on the QPF progs the first two periods. For
pops with go some 10-20%s early this evening for the plains. No
pops on Sunday. For temperatures, Sunday`s highs are 0.5-1.5 C
warmer than this afternoon`s. The Denver daily record high for
August 9th is 98 F. That looks obtainable.

.LONG TERM...(Sunday night through Saturday)
Issued at 1246 PM MDT Sat Aug 8 2020

Still no changes in the forecast for the upcoming week with continued
hot and mainly dry conditions. The exception will be some slight
cooling on Monday.

On Sunday night and Monday, a weak cold front will move southward
across the plains Sunday night with a cooler airmass in place for
Monday but unfortunately not much moisture to work with.
Temperatures will cool a bit into the 80s across the plains. The
cooler low levels will keep the airmass fairly capped on the
plains with just a slight chance of a late day shower, mainly
mountains and higher terrain.

From Tuesday through Thursday there will be a light westerly flow
aloft with high pressure ridge across much of the southern plains.
Can`t see much more than isolated late day showers through the
period while temperatures climb back into the 90s across the
plains. For the end of the week, high pressure ridge aloft builds
further west and towards around the 4 corners region by next
weekend. Broken record continues with persistent forecast for
unforeseeable future.

Not much happened at DIA with the cold front that was moving
towards the airport earlier today. Normal drainage winds are
expected overnight. Same with the Sunday, normal diurnal patterns
are expected. There shouldn`t be any rainfall at DIA tonight or
Sunday. There should not any ceiling issues either.

There will be elevated fire danger across much of the forecast
area by Sunday afternoon with low relative humidities and above
normal high temperatures.  Winds will be pretty weak however
across all of the CWA.

For next week elevated fire danger continues with the dry
conditions/low humidities but not much in the way of winds. Driest
conditions will be in the mountains and adjacent plains with
slightly higher humidities across the far eastern plains.
