Area Forecast Discussion
National Weather Service Bismarck ND
215 PM CDT Wed Apr 26 2017

.SHORT TERM...(This evening through Thursday)
Issued at 215 PM CDT Wed Apr 26 2017

Mid-afternoon radar mosaic shows the main axis of precipitation
extending from parts of western Minnesota into southeast North
Dakota and northeast South Dakota. Global and short term hi-
resolution models all generally agree the snow should gradually
diminish this afternoon, ending this evening. The Winter Weather
Advisory still looks good (expiring at 7 pm central time) with
brief visibility reductions possible and additional accumulations
of an inch or two.

A dry day is expected for Thursday with highs in the 40s to near
50.

.LONG TERM...(Thursday night through Wednesday)
Issued at 215 PM CDT Wed Apr 26 2017

The long term period will start off fairly quiet with the main
story becoming the chances of precipitation towards Sunday night
and Monday. Temperatures will start off a little on the cool side
of normal, but should return to near normal this weekend. For
Sunday night and Monday, one wave will pass to our south, while
another northern stream wave moves across the Northern Plains.
This will increase rain chances for Sunday night into Monday
across the forecast area. Thermal profiles generally support rain
through most of that period.

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 215 PM CDT Wed Apr 26 2017

MVFR and local IFR ceilings with snow and areas of light rain or
light freezing drizzle will impact the southern James River valley
today, but confidence is waning on precipitation impacts at KJMS.
Will continue with VCSH at KJMS through the afternoon. Still
expecting MVFR/IFR conditions to continue at KJMS through the
TAF period.

Otherwise MVFR at KBIS and KDIK had already dissipated or should be
soon after 18Z. By tonight MVFR conditions may stray back
into KBIS, but KMOT-KDIK-KISN should remain VFR.
