Area Forecast Discussion
National Weather Service Duluth MN
646 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 00Z TAFS through 00Z Wednesday evening)
Issued at 646 PM CDT Tue Mar 28 2017

Generally VFR conditions will prevail through the period as high-
level clouds gradually increase and a light east-southeast wind
develops through Wednesday. MVFR stratus is possible at HYR and
DLH and have hinted towards this possibility in the latest
TAFs. Short-range guidance is not very bullish on this
possibility, but continued previous forecast trend of including
scattered to at times broken MVFR deck late tonight into Tuesday
morning. Any stratus that develops may stick around as increasing
high-level clouds would limit solar heating potential on
Wednesday.
