Short term (today and tonight)
issued at 318 am cdt Sat apr 21 2018
overall quiet weather is expected this week. A large cut-off low
pressure system moving through the central plains will be the main
driver of weather today. This morning's overcast skies will
continue into the afternoon, with chances for sprinkles or light
rain for the tri-state area. Lift is weak with these showers, and
dry air near the surface will minimize accumulations. By the
evening, drier air moving in aloft will reduce the chance for
sprinkles and begin to break up clouds. Temperature in the upper
40s to low 50s are forecast, with light east winds.
Long term (Sunday through Friday)
issued at 318 am cdt Sat apr 21 2018
a warming trend is expected Sunday and especially Monday, as a upper
level ridge to the east and an approaching low allow warmer low-
level southerly flow to reach the region. Highs look to reach into
the 60s on Monday, which will be near normal for this time of year.
A quick moving shortwave trough moves through on Tuesday, bringing
our next chance for light rain. A tightening pressure gradient will
bring cooler, breezy north winds, gusting into the 20 mph range;|
nothing out of the ordinary for this time of year, but will likely
be noticeable given the warmth and very light winds over the
preceding days. Temperatures will remain slightly below average
for the second half of the week.
Aviation (for the 12z tafs through 12z Sunday morning)
issued at 637 am cdt Sat apr 21 2018
mid-level overcast skies are likely though 21 1800z, with scattered
light rain showers. During the afternoon, rain chance decrease and
clouds begin to thin, but multiple scattered cloud layers are likely
through Saturday night. Winds will be light over the next 24

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
