Area Forecast Discussion
National Weather Service Grand Forks ND
257 PM CDT Mon Sep 26 2016

.SHORT TERM...(This evening through Tuesday)
Issued at 257 PM CDT Mon Sep 26 2016

Main forecast challenges will be decreasing winds tonight followed
by frost chances tonight and Tuesday night. Winds have generally
been a little lower this afternoon than they were yesterday, but
there are still a few sites that have been brushing with advisory
criteria again. However, it has not been long enough or widespread
enough to justify another advisory. Morning showers over the far
northeast have moved east of the FA, so will not include any more
mention of them tonight. Winds will get lightest west of the Red
River Valley tonight, and with the dry air in place should see
some frost there. For that reason issued a frost advisory for that
area tonight. Expect less wind on Tuesday, but there could be a
few more showers in the far east.

.LONG TERM...(Tuesday night through Monday)
Issued at 257 PM CDT Mon Sep 26 2016

Tuesday night through the end of the week will be predominately
dry with moderating temperatures. First concern will be Wednesday
morning with the SFC high pressure system over the FA there will be
frost potential along and west of the valley. Clouds and better
mixing to leave the eastern areas with less potential for temps to
drop off. 500mb ridging continues to build over the central US and
into southern Canada Wednesday into Thursday and Friday. This will
allow daytime highs to reach into the upper 60s and low 70s
Wednesday through Sunday. Some chance PoPs work into the FA with
500mb SW flow by Sunday and Monday with moisture limited.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 103 PM CDT Mon Sep 26 2016

Gusty northwest winds will begin to decrease this evening,
becoming lightest at KDVL overnight. Some SCT to BKN clouds have
been filling back in across northwest MN, affecting KTVF and KBJI.
These should fade away later this afternoon. However, guidance
shows some even lower ceilings building back westward through
KBJI and KTVF later tonight into early Tue. Kept some lower
ceilings at these two locations for then.


ND...Frost Advisory from 1 AM to 8 AM CDT Tuesday for NDZ006-007-014-
