Area Forecast Discussion National Weather Service Duluth MN 619 PM CDT Wed Aug 5 2020

SHORT TERM. (This evening through Thursday night) Issued at 342 PM CDT Wed Aug 5 2020

A short wave in western Minnesota is currently moving southeast, and it is possible that there could be a stray shower or thunderstorm in the southwestern-most part of the CWA this afternoon. Those chances for rain are diminishing very quickly in the high-res models, though. Otherwise, fair weather cumulus will fill the sky today across the region with highs in the mid 70s and cooler near the lake.

Tonight, a LLJ combined with an approaching ridge will advect warm, humid gulf air into the Northern Plains, slowly increasing our highs Thursday and Friday for a warm end of the week.

LONG TERM. (Friday through Wednesday) Issued at 342 PM CDT Wed Aug 5 2020

Friday, a low developing in eastern Canada is expected to strengthen and an associated cold front should move east across the Northland Friday night into Saturday. This will bring more chances for showers and thunderstorms. There is a chance some of these storms could become severe, but it is pretty marginal. Global models show upper level forcing occurring east of the 1000-2000 J/kg of MLCAPE and with 20-30 kt bulk shear. There could be a threat for some heavy rain, with PWATs ranging from 1.5-2.0 inches.

We'll get a short break from the rain Sunday afternoon before another cold front sweeps through the Northland with more rain chances Sunday night through Monday. Once that moves east, another ridge moves into the Midwest for cooler temperatures in the mid week from northwesterly flow.

AVIATION. (For the 00Z TAFS through 00Z Thursday evening) Issued at 618 PM CDT Wed Aug 5 2020

VFR conditions currently in place for the Northland. Overnight there is potential for HIB to see fog development, however conditions are fairly similar to yesterday which didn't yield any fog in the early morning hours. Confidence in fog forming is low. Any fog that does manage to develop is not expected to be widespread and will quickly erode from the morning sun. Southerly winds will stream back into the Northland tomorrow with afternoon clouds, look for VFR conditions to continue.

MARINE. Issued at 342 PM CDT Wed Aug 5 2020

Marine weather looks quiet over the next 48 hours. Light southwesterly winds will continue tonight into Thursday before turning southerly to easterly late Thursday evening. Waves over the next 48 hours are not expected to exceed 2 ft.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
