9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Midlevel water vapor reveals a shortwave trough lifting northeastward across northwestern NE resulting in scattered showers. At the surface, a broad trough was positioned across the high plains from eastern nm through the western dakotas. The benign weather pattern is expected to continue through Tuesday with temperatures remaining well-above average. Overnight lows tonight will reach the 70s with highs Tuesday afternoon in the 90s. Coupling the heat with the high humidity will yield an another day with heat indicies in the upper 90s. Long term (Tuesday night through Monday) issued at 328 pm cdt Mon sep 16 2019 transitioning into the extended period, a few thunderstorms are possible late Tuesday night into Wednesday morning as a shortwave trough ejects across the northern plains shunting the aforementioned |
surface trough into southern NE before stalling. Another round of showers storms are possible late Wednesday night into Thursday morning along the stalled frontal boundary across far northern ks southern ne. Better chances for thunderstorm activity arrive this weekend as the main midlevel trough ejects across the northern plains, shunting the surface frontal boundary into the area. Temperatures look to remain well-above average through much of the weekend with highs in the 80s and 90s. The previously mentioned cold front will likely result in closer-to-normal temperatures with highs in the low 80s by Sunday. Aviation (for the 18z tafs through 18z Tuesday afternoon) issued at 1234 pm cdt Mon sep 16 2019 vfr conditions are expected through the TAF period. Southerly winds will remain near 6-12 kts through 00z before decreasing through the night and increasing after sunrise Tuesday morning to 9-15 kts. In addition, marginal llws conditions are expected tonight as a 30-35 kt LLJ near 1 kft overspreads the terminals. Top watches warnings advisories None. Short term... Baerg long term...

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 numerious 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. |
