SHORT TERM. (Today and tonight) Issued at 343 AM CDT Wed Aug 5 2020
Convection continued to move southeast across eastern Nebraska ahead of a mid level shortwave within a zone of 850-700mb frontogenetic forcing at 08Z. The convection should continue to move off to the southeast early this morning and keep to the east of far northeast Kansas.
Today morning clouds should give way to a mix of sun and clouds this afternoon with highs ranging from the upper 70s to lower 80s. Tonight convection will be possible late as convection may move into northeast Kansas from Nebraska aided by a mid level wave and across north central Kansas from high plains convection aided by a subtle wave and moderate low level jet with moisture flux into north central Kansas. Lows tonight will be more mild with lows in the 60s.
LONG TERM. (Thursday through Tuesday) Issued at 343 AM CDT Wed Aug 5 2020
Thursday morning convection may continue before clearing out by early afternoon in east central Kansas. Temperatures are expected to be a little warmer with highs in the low to mid 80s. Additional convection is possible Thursday night as another subtle wave moves out into the central Plains and within the nose of the low level jet across eastern Kansas and western Missouri where the best theta advection is expected.
Friday morning convection moves out with mostly dry conditions expected in the afternoon and evening hours. Isolated convection may occur again across eastern Kansas into Missouri within a zone of isentropic lift as the low level jet increases from the southwest and the presence of a subtle PV anomaly.
An upper level ridge builds in for the weekend bringing with it a return to highs in the 90s and lows in the 70s. Nocturnal convection will be possible and linger into the morning hours. Chances remain low and dependent on weak mid level waves moving out across the region. The ridge flattens early next week with a more zonal flow across the Plains keeping small chances of convection possible.
AVIATION. (For the 12Z TAFS through 12Z Thursday morning) Issued at 535 AM CDT Wed Aug 5 2020
VFR conditions are expected through the period. Convection later tonight after 09Z is expected to remain north of the terminals so will not include mention at this time. Winds become southeast to south after 15Z under 10 kts.

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.
