AREA FORECAST DISCUSSION National Weather Service Hastings NE 624 PM CDT Sat Jul 11 2020

SHORT TERM. (This evening through Sunday) Issued at 255 PM CDT Sat Jul 11 2020

Biggest issue for the short term will be determining how realistic the NAMnest is with convection generated for Sunday.

We will remain under northwest flow aloft, situated on the northeast side of a strong southwestern upper level high that has been baking the southwest into Texas as of late. The cold front/trough should be far enough southeast today to keep convection this afternoon southeast of the CWA, although probably a close call in the early afternoon. We may have some showers near our southern CWA border in KS, and perhaps get a decent gust of wind, but there is enough CIN to keep growth capped for the most part.

Dry weather should prevail with subsidence today continuing into tonight and limited CAPE tomorrow as return flow just starts getting going by Sunday afternoon. Not really buying into the NAMnest showers/thundershowers most of the day Sunday with the surface high nearby with limited instability. Looks like NAMnest is a true outlier and will ignore for now.

LONG TERM. (Sunday night through Saturday) Issued at 255 PM CDT Sat Jul 11 2020

Biggest issue for the long term will be timing of a cold front and mid-level trough/vort max for Monday night and what our severe chances will be for this period.

There looks like decent agreement among numerical models that strong height falls as a result of a shortwave trough moving into the Plains will occur, and will help spawn thunderstorm development by Monday evening. Enough return flow by then will push dewpoints well into the 60s, providing us with more instability. Severe parameters clearly indicate the severe potential for Monday evening, and would probably start heading into the CWA shortly after 00Z.

Decent agreement among models of a cool down in the Tuesday/Wednesday time frame, but a warm-up then ensues as a warm front heads back north of the area by Thursday. We will still have periodic small chances of thunderstorms in the long term as we remain under predominant west/northwest flow with small pieces of energy giving us a chance of precip for much of the long term, although in reality, most of the CWA will be dry for the majority of the long term forecast.

The subtropical high builds back strong by late next week, giving us above normal temperatures with heat indexes pushing 100 degrees.

AVIATION. (For the 00Z KGRI/KEAR TAFS through 00Z Monday) Issued at 622 PM CDT Sat Jul 11 2020

A surface high will settle into the area tonight and will slowly move to the east tomorrow. Winds will be generally light from the north and will gradually turn toward the southeast.

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.
