National Weather Service Pueblo CO
139 PM MDT SUN JUL 3 2016

.UPDATE...
Issued at 137 PM MDT Sun Jul 3 2016

Short wave coming out of the mtns is initiating convection over
the mtns and adj plains. HRRR is showing convection will likely to
continue and drop east-southeast over the plains this afternoon. A
couple of locally strong storms pssbl over plains especially s of
US50. Cant rule out some locally heavy rain in the mtns...as Sand
Dunes got over 2" yesterday. \/Hodanish

.SHORT TERM...(Today and tonight)
Issued at 345 AM MDT Sun Jul 3 2016

This morning an upr disturbance is bringing showers and some isold
thunder to the contdvd.  The NAM shows the upr disturbance slowly
moving southward ovr the forecast area thru the day.  The HRRR shows
the activity over the contdvd and possibly affecting the nrn Sangres
and the Pikes Peak area into about midmorning, and then briefly
dissipating. Showers/tstms show up in the HRR again around 17-18Z
ovr and nr the mtn areas, and then spread east and south ovr the
forecast area in the afternoon and evening as the upr wave moves
south. There will still be the threat of locally heavy rainfall,
which could cause problems if it falls in urban areas, on burn scars
or in locations that have had heavy rain in the last few days.  High
temps today are still expected to be a little below average.

By late evening it looks like most, if not all of the convection
should end as the upr wave moves out of the area and an upr ridge
builds ovr the state.

.LONG TERM...(Monday through Saturday)
Issued at 345 AM MDT Sun Jul 3 2016

...A warming and drying trend for the middle of the week...

Monday-Tuesday...Generally weak westerly flow aloft progged across
the region on Monday gives way to increasing westerly flow aloft
across the area on Tuesday, as an upper trough moving across the Pac
NW continues into the Northern Tier on Tuesday. Models continue to
indicate a minor disturbance moving through the flow on Monday,
supporting scattered showers and storms developing across the higher
terrain Monday afternoon, with a few storms moving east across the
plains through the evening. Temperatures on Monday look to be around
seasonal averages. Drier air within the increasing westerly flow on
Tuesday helps to mix out the atmosphere with warmer and drier
conditions expected. There will be enough residual moisture to
support isolated afternoon and evening storms, mainly over the
higher terrain, with convection expected to be more high based.

Wednesday-Thursday...Moderate westerly flow aloft continues across
the region, as Northern Tier upper trough continues to translate
east. Warm and dry westerly flow helps to boost temperatures across
the area on Wednesday with diurnal isolated high based storms
possible over and near the higher terrain. Wednesday could be a
critical fire weather day across portions of the area, though will
have to see how recent rainfall has affected fuels across the area.
Passing Northern Tier system looks to send a weak front across the
area on Thursday, supporting slightly cooler temperatures and
slightly better chances of storms across the area.

Friday-Saturday...Generally dry west to southwest flow aloft progged
across the area into next weekend keeping temperatures at or above
seasonal averages and chances for mainly high based convection over
and near the higher terrain through the period. However, the ECMWF
still keeps more available moisture across the area and is
indicating better chances of diurnal storms both Friday and
Saturday. Time will tell.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1126 AM MDT Sun Jul 3 2016

Scattered tsra will be possible at all three the taf
sites...kpub...kals and kcos this afternoon and early evening.
Brief pds of mvfr could occur due to precip/cigs. Otherwise expect
vfr. Winds will be light except in and near tsra.
