Area Forecast Discussion
National Weather Service Duluth MN
335 PM CDT Tue Mar 28 2017

.SHORT TERM...(This evening through Wednesday)
Issued at 322 PM CDT Tue Mar 28 2017

The northland will be under the influence of high pressure at the
surface and aloft while a deep long wave trough affects the
southern portion of MN and WI. The surface low, which has been
taking shape today in the southwest U. S. will move northeast into
the Central Plains on Wednesday. Moisture streaming northward
ahead of this low will provide more clouds to the northland which
will in cooler temperatures.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 322 PM CDT Tue Mar 28 2017

The long term forecast is relatively quiet. Near-zonal flow will
continue for much of the period, maintain near to above normal
temperatures with daytime highs generally in the 40s and 50s. High
pressure will promote fairly clear skies Thursday and Friday, but a
passing shortwave trough could bring some light precipitation (rain
and snow) Saturday. The GFS is much more aggressive with this trough
and precipitation compared to the mostly dry European and Canadian
models, so not too confident if the forecast area will get
precipitation. Southerly flow will develop Sunday and provide a
warmer and dry day. The European and GFS suggest there could be a
period of wetter weather just after this period, around Monday night
and Tuesday.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1232 PM CDT Tue Mar 28 2017

High pressure will continue to promote clear skies and light wind
speeds today. Light easterly flow will develop late today and
tonight and there are some model indications there could be some
cloud cover in the 1 to 3 kft range late tonight and early
Wednesday. The RAP, NAM, and GFS models are indicating some
saturation within that layer late tonight. The KHYR has the best
chance of seeing MVFR ceilings, and my confidence is high enough
to include it within the latest forecast. The KDLH area could get
it, too, but not as confident to forecast it yet.
