Area Forecast Discussion National Weather Service Duluth MN 341 AM CDT Wed Jul 15 2020

SHORT TERM. (Today and Tonight) Issued at 341 AM CDT Wed Jul 15 2020

Today a shortwave moving southeast from Canada should bring chances for scattered showers and thunderstorms in northeastern Minnesota, otherwise the rest of the Northland is expected to stay dry. Wednesday night, an upper level trough is expected to make its way into our area and the Northland will see chances for more showers and thunderstorms late. No severe weather is expected from either of these systems.

LONG TERM. (Thursday through Tuesday) Issued at 341 AM CDT Wed Jul 15 2020

An upper trough will extend south through Minnesota Thursday morning with a weak cold front west of the Northland. The front will move east through the area Thursday and weaken or wash out Thursday night into Friday. There will be a chance for showers and thunderstorms as the front moves through with chances highest over northern Minnesota. Severe storms are not expected.

Dry weather returns for Friday due to brief ridging. Chances for showers and storms return Friday night into Saturday. A stronger cold front, a shortwave, a low level jet of 30 to 35 knots, and plenty of instability (especially over our southern area) will all be present. The models are in pretty good agreement at this time and we have high POPs across most of the Northland. Given the instability, forcing, and adequate deep layer shear, there will be a threat for severe storms Friday night, especially across central into northern Minnesota. In addition to the severe threat, heavy rain will be possible with PWAT values 1.6" to 1.8" per the GFS and the low level jet. Showers and storms will continue to move across the Northland Saturday and the ECMWF and Canadian are more progressive with the front versus the GFS. We have POPs all day across the Northland but we expect chances will be greatest in the morning and we may be able to pull back in the afternoon once better agreement among the models occurs. Saturday could be a warm one with highs from the mid eighties to around ninety. The one issue may be precipitation coverage and cloud debris and if the slower frontal movement occurs then we will likely be too warm.

The rest of the period will feature periodic chances for showers and storms but chances and coverage isn't expected to be high. Highs from Sunday into Tuesday will be from the upper seventies to mid eighties.

AVIATION. (For the 06Z TAFS through 06Z Wednesday night) Issued at 1238 AM CDT Wed Jul 15 2020

High pressure will allow areas of fog to develop tonight at HIB, HYR, and possibly BRD. Southwest winds will strengthen and become gusty on Wednesday in response to an approaching shortwave trough aloft. A few scattered showers are not out of the question over northern Minnesota during the afternoon and early evening, but have kept mentions out of the forecast for now due to uncertainty in timing and locations. Storms may avoid the terminals entirely. Winds will subside Wednesday evening.

MARINE. Issued at 341 AM CDT Wed Jul 15 2020

Southwest winds of 8 to 15 knots will occur today into tonight with some higher gusts. There may be a few thunderstorms this afternoon and evening, mainly along the North Shore. Southwest winds will continue Thursday and be from 10 to around 10 knots with higher gusts. Thunderstorms will again be possible, especially in the afternoon. Winds will be lighter Thursday night with most areas dropping to 10 knots or less.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
