Marine Weather and Tide Forecast for Montezuma, KS

DISCUSSION
Issued at 1030 PM CDT Mon Jun 8 2026

Radar and satellite imagery depicted an intense MCS diving southeast through central Kansas. Outflow from this complex was evident on radar passing south through SW KS. Despite high instability and boundary layer moisture, the SW KS DDC CWA has been protected from severe storms today by a strong capping inversion. 00z DDC sounding measured 15.5C at 700 mb, and this elevated mixed layer squashed any attempt at convection in SW KS Monday. Winds are variable in direction currently, but will trend light southeasterly through sunrise. With continued moisture advection, temperatures will struggle to fall below 70 at many locations Tuesday morning.

After 10 am Tuesday, southwest winds will increase, averaging 20-30 mph with gusts near 40 mph. Models show unidirectional SWly flow through the lower troposphere most of Tuesday.
With 850 mb temperatures in the 28-29C range, downslope compression will send temperatures soaring to near 100 all locations by 4 pm. Slightly drier air is projected Tuesday, which should keep heat indices across the southeast zones just below heat advisory criteria (105).

00z NAM forecasts a 996 mb surface cyclone near Syracuse at 4 pm Tuesday as the next shortwave approaches in SWly midlevel flow aloft. Strong instability will be present by afternoon, with CAPE near 3000 J/kg projected. Models show strong forcing for ascent ahead of Tuesday's wave, timed well with the diurnal heating cycle. Unlike Monday, convection initiation should be much easier Tuesday, with rapid development expected across western zones around 4 pm. Any high based supercells may produce hail initially, but a strong trend to linear segments/bows in an inverted-v environment will support severe outflow wind gusts as the primary risk, along with areas of blowing dust especially western zones. NBM pops have increased across western zones for Tuesday on this update, and this trend was accepted. SPC 15% wind probabilities and conditional intensity are appropriate, with higher wind probability possibly required.

The heat will continue Wednesday, with afternoon temperatures again near 100. A dry cold front will race through SW KS Thursday morning, followed by north winds Thursday ushering in noticeably milder temperatures in the 80s. There may be a thunderstorm in the southeast zones on this front Wednesday evening, but most locations will be dry.

Friday appears dry with seasonable temperatures. Showers and thunderstorms are forecast to return over the upcoming weekend, and NBM pops continue to trend upward through this timeframe.
One or more MCSs in this pattern will likely continue to chip away at the SW KS drought.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
Issued at 1030 PM CDT Mon Jun 8 2026

VFR is expected to prevail through this TAF period. Current variable winds will trend light southeast overnight through 12z Tue. VFR/SKC or scattered midlevel clouds are expected overnight. After 15z Tue, SW winds will increase at all airports, gusting near 30 kts. Winds will back more southerly and remain strong/elevated through 00z Wed. Models suggest a line of thunderstorms may impact all of the airports during the 00-03z Wed time frame, with outflow wind gusts near 50 kts the primary risk. For now, included VCTS/CB mention in all TAFs, but convective TEMPO groups are expected to be required.

DDC WATCHES/WARNINGS/ADVISORIES
None.
