AREA FORECAST DISCUSSION National Weather Service Sioux Falls SD 1139 AM CDT Sat Jul 4 2020
SHORT TERM. (Today and Tonight) Issued at 359 AM CDT Sat Jul 4 2020
Upper level ridging will continue to dominate across the region today, and in the absence of any significant lifting mechanism and subsidence it should remain dry. Thermal profiles are similar to yesterday, so looking for highs again in the upper 80s to lower 90s. With dewpoints in the upper 60s, the afternoon heat index will be in the 90s.
Any convection tonight looks to remain to our north and west. It will be another mild night with lows in the upper 60s to lower 70s.
LONG TERM. (Sunday through Friday) Issued at 359 AM CDT Sat Jul 4 2020
The upper level pattern begins to change by later on Sunday as the ridge begins to flatten as upper level energy deepens and drifts across southern/central Canada. It still appears that most of the day will be dry, and again hot and muggy with highs around 90. By Sunday evening a frontal boundary begins to approach the western portions of our CWA, and could kick off a few showers and thunderstorms over that area at night.
There is no significant cool down on the horizon, with temperatures remaining in the upper 80s to lower 90s through next week, perhaps warming into the mid 90s for some locations on Wednesday. With a more zonal upper level pattern in place, shower and thunderstorm chances will be better than recent days as a series of shortwaves move across the region. At this point, the better chances of precipitation will occur on Monday night into early Tuesday as the first shortwave slides through the area, then again on Wednesday night.
AVIATION. (For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1138 AM CDT Sat Jul 4 2020

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. 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.
