Short term (this evening through Friday)
issued at 228 pm cdt Thu mar 21 2019
low pressure continues to settle southeast across indiana this
afternoon. Still a lot of cloud cover over our area, and the
western fringes of it showed some diurnal type development.

However, the trend continues to be with a west-east clearing this
afternoon as previously indicated. Will stick with a mostly clear
sky much of the night. However, clouds will increase again from
the north late, as a weak boundary passes. Greatest cloud cover
will be early Friday morning with this feature, and mainly over
the eastern cwa. This will keep highs a bit cooler across the
eastern CWA again on Friday, with warmer conditions over the
southwest with greater sun.

Long term (Friday night through Thursday)
issued at 228 pm cdt Thu mar 21 2019
upper level ridge edges into the mississippi valley as we start
the weekend, with abundant sunshine on tap for Saturday. However,
the upper low currently spinning just west of las vegas will move
into the central plains by late Saturday. Showers will overspread
the forecast area beginning late Saturday night, as this feature
moves toward the mid-mississippi valley. Have maintained a mention
of thunder Sunday afternoon, with a few hundred j kg of mucape
still indicated by the gfs. By Monday, the storm system will be
pushing southeast, but rain chances will linger in most areas at
least into the morning.

Broad upper ridge progged to build across the nation's mid section
into mid week, which will bring a nice warming trend by Wednesday.

Highs in the 50s should return by Wednesday, with 60s Thursday. Next
chance of showers will be on Thursday, with some warm advection.

Aviation (for the 18z tafs through 18z Friday afternoon)
issued at 1214 pm cdt Thu mar 21 2019
ifr conditions continue to hug the indiana border at midday, but
ceilings mainly at MVFR levels at the moment. Western flank of the
cloud deck shows more diurnal type development, and ceilings near
kspi and west are now above 3,000 feet. Think the general trend
will be for increasing ceilings over the next few hours, as skies
start to clear from west to was, and skies should be mostly clear
by 00z. Gusty northwest winds will settle down a bit this evening,
then pick up again on Friday morning after passage of a frontal
boundary.

Ilx watches warnings advisories
None.

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.
