Area Forecast Discussion...UPDATED
National Weather Service Grand Forks ND
1241 PM CDT Sun Jul 23 2017

.UPDATE...
Issued at 1241 PM CDT Sun Jul 23 2017

Tweaked temperatures down a bit along the Red River valley, as
cloud cover continues to limit heating. Expect low level clouds
to begin clearing more quickly this afternoon from north to
south, but may remain longer in the valley than other areas.

&&

.SHORT TERM...(Today and tonight)
Issued at 250 AM CDT Sun Jul 23 2017

Quiet day ahead as surface high pressure builds into the forecast
area. Band of sc associated with weak inverted trough may
initially slow warmup this morning and cooler airmass in place so
limited temperatures to the 70s today. Coolest readings over the
se, last to see any clearing.

Surface high shifts east tonight setting up return flow and warm
advection. Mixing will hold temperatures generally in the mid 50s
to lower 60s.

.LONG TERM...(Monday through Saturday)
Issued at 250 AM CDT Sun Jul 23 2017

Temperatures should recover back to seasonal averages Monday as
mixing and warm advection increases.

Models slower in tracking next upper low across southern Canada
and now looking like better chances for pcpn will be after
midnight and likely closer to Tuesday morning. Coverage also in
question as 12C and higher 700mb temperatures nearly as far north
as highway 2.

Better chances for pcpn will be Tuesday as boundary crosses the
forecast area. With timing of boundary at prime heating, best
chances for showers and storms will be over the Mn portion of the
forecast area. Seasonal temperatures will continue but may be
governed by degree of cloud cover.

Wednesday-Saturday...Looks like this period will offer a nice
stretch of weather, if you enjoy daytime temperatures near 80F,
mainly dry weather, and relatively light winds. Models in decent
agreement with the large scale pattern which places the forecast
area under the control of SFC high pressure for much of the period.
Return flow commences at some point late in the week or into the
weekend, providing thunderstorm chances.  Predictability too low to
say what impacts can be expected.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1241 PM CDT Sun Jul 23 2017

IFR/MVFR cigs along the Red River Valley and eastward are expected
to continue scattering and clearing out from north to south
through the afternoon. Light winds and mostly clear skies tonight
and into early Monday as high pressure moves in.
