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.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus63 karx 191851 afdarx area forecast discussion national weather service la crosse wi 150 pm cdt Mon aug 19 2019 Short term (tonight through Tuesday) issued at 150 pm cdt Mon aug 19 2019 upper level shortwave trough slides east across the northern plains this evening with the low level jet 850 mb moisture transport nosing into the shortwave by 09z as it shifts across northern ia. Convection should take off in earnest as this occurs, and meso models show just that with rapid development between 06-09z over northwest ia, dropping southeast into western il toward 12z. Despite overnight timing, there looks to be some elevated instability to work on along with favorable shear, moreso in the 0-3 km layer. Expect some strong to severe storms across ia overnight. Current location would keep the bulk of this threat just southwest of the local forecast area. Certainly a scenario that bears a close watch, especially for northeast ia. As the MCS exits southeast, some models (esp rap) hang an inverted trough piece of upper level energy northwest of mcv. In those scenarios, enough low level saturation also hangs back, providing ingredients for cont shower isold storm chances across the south into the afternoon. Don't anticipate any strong severe threat with any of this activity. Will hold small pops for now. Another bit of upper level energy looks to slip east southeast across northern mn Tue morning, into northern wi by the evening. Differences in timing between the variety of models... With latest hrrr about 12 hours quicker on bringing in convection north of i-94 compared to the 12z nam12. That said, many of the other models only produce a smattering of showers storms. Going against the convection is no little tap to gulf moisture (focused south with that exiting mcs), cloud cover across the south from the MCS (how extensive, thick), and bufkit soundings suggest capping that could will need to be overcome (either warming or by the front shortwave). What does get going will have some instability to work with - rap suggests upwards of 2500 j kg of SBCAPE over northern wi by 00z Wed and potentially +30 kts of effective shear. If that manifests, enough |
support for some stronger isold severe storms. A lot of "ifs" though for Tue afternoon evening... And confidence is not high at this time with how it will playout. Long term (Wednesday through Monday) issued at 150 pm cdt Mon aug 19 2019 models in good agreement with the overall, big picture for the last half of the week. Upper level shortwave trough slated to drop southeast across the great lakes Wed wed night. Little saturation to work on though - most of that will be cleared south southeast with the Tue system. A sfc high then progged to build in from the west for Thu Fri while the axis of an shortwave ridge a loft treks east across the northern plains. Should see a dry end to the work week, with temps likely a few degrees below the late aug normals. The ridge quickly shifts east for the weekend, allowing for a shortwave trough to nudge in from the west. Showers storm chances will accompany the trough and its associated sfc front. Should also see a bump up in temps as winds turn more southerly. Aviation (for the 18z tafs through 18z Tuesday afternoon) issued at 1231 pm cdt Mon aug 19 2019 vfr conditions expected into the overnight hours with clear skies and light winds. Fog is possible in the river valleys, but confidence is somewhat low as debris cirrus from ongoing storms to the south could hinder its development, along with increasing winds just above the surface toward the early morning hours. Looks like storms should stay well south of the TAF sites, but there are some hints of an associated MVFR cloud deck sneaking into rst by mid- morning. For now, keeping it at bkn035, but will need to monitor trends in future issuances. Arx watches warnings advisories Wi... None. Mn... None. Ia... None. Short term...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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. |
