Forecast weather conditions for Thursday and Friday
Note: Below are three different computer models and their rainfall potential through 7 PM Friday. Euro continues to be the drier model while the GFS model remains a wetter solution for the Twin Ports area. Expect some rain showers in Duluth and Superior Thursday afternoon into Friday, but based on the trends I’ve been seeing in the model runs today, I don’t think this is going to be a major rain event or an all day soaker in the Duluth area Thursday or on Friday.
High pressure was over the central Great Lakes late this afternoon with low pressure and an upper level trough over the northern Plains. Southerly winds returned to the Northland today along with milder temperatures as high topped out in the mid 70s to low 80s. We’ve had a mix of sun and clouds throughout the day.
Dry tonight under a partly to mostly cloudy sky, lows will be in the lower 50s to lower 60s.
Thursday will feature partly to mostly cloudy skies. Still on the mild side with highs ranging from the lower 70s to lower 80s although some spots in far northern Minnesota could make a run at the mid 80s if clouds don’t thicken up too much.
Should see some rain showers spread into western-southern portions of the Northland Thursday morning or early Thursday afternoon, these showers will then lift farther north later in the day. Once the showers arrive (assuming they do) temperatures will cool off just a bit, this is especially true for southern/southwest portions of the Northland as those areas will have the best chance for some showers on Thursday along with thicker cloud cover compared to areas farther to the north.
Note: Overall the trend is for less rain in our area for Thursday and Friday as low pressure takes a slightly farther south track compared to what it looked like it would do over the last few days. Still expecting some rain showers at times Thursday and Friday but an all day rain event is unlikely, and rainfall amounts shouldn’t be very significant in our area.
