SHORT TERM. (Today and tonight) Issued at 1238 AM CDT Sat Aug 8 2020
At midnight CDT a cold front was progressing through east central North Dakota, currently extending from near Devils lake southwest to near Linton ND. Much drier air is moving into the state behind the front. Dewpoints are already falling into the mid 40s across western ND, and to the east dewpoints are in the lower 70s at places like Linton and Jamestown. The drier air moving east will end the thunderstorm threat for the remainder of tonight, so have taken the chances out.
The low dewpoints to the west do point to pretty low afternoon RH values across the west. We updated the min RH and it looks like mid to upper teens are expected western third of teh state. However winds will remain very subdued, less than 10 mph so do not see critical fire weather today.
LONG TERM. (Saturday night through Friday) Issued at 200 PM CDT Fri Aug 7 2020
Instability and precipitation chances increase Saturday evening and night across the southwest, expanding north and east overnight. Severe weather will likely remain south of the state Saturday night and east of the forecast area on Sunday. A few stronger storms may be possible across the southern James River valley Sunday afternoon, however.
Otherwise, after Sunday, general height rises aloft with a return to mainly zonal flow should maintain fairly low chances for thunderstorms through Tuesday. It is worth noting that CIPS extended analogs have been consistent in showing a strong signal for severe weather towards the end of the work week. We have a very long way to go to work out any specific details, but this will be a time period that we will be watching closely as we may become fairly active again.
AVIATION. (For the 06Z TAFS through 06Z Saturday night) Issued at 1238 AM CDT Sat Aug 8 2020
VFR expected across the region. At midnight CDT a cold front across central North Dakota will move east to Minnesota today. Dry high pressure will move to and remain over central North Dakota.
BIS WATCHES/WARNINGS/ADVISORIES. NONE.

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.
