Is this today or tomorrow JoMo?? And also what does it look lik for us monday and tuesday here in jln JoMo???

That's today but we're capped with no forcing so our chances of getting a storm to form are slim to none. Monday evening it looks like a line of storms will move through here. And maybe some more storms on Tuesday depending on timing of the front.

I left the NERN KS target, in fear of the cap, but if something does go, its gonna be hell in that area! Decided to try something new, and go uplsope today.

HRRR is painting some nasty weather for KC...and more rain for the Missouri River Basin where the levees have been overran in Atchinson County, MO.

alot of good porn from the DSM office regarding tomorrow's potential and also low topped supercells and tornadoes on tuesday as well..

A WEAKENING MCS IS EXPECTED TO BE ONGOING BY 12Z TOMORROW MORNING.

THE EXACT PLACEMENT OF THIS MCS...AND THE OUTFLOW BOUNDARIES IT

LEAVES BEHIND WILL HAVE A LARGE IMPACT THE TIMING AND PLACEMENT OF

CONVECTIVE INITIATION MONDAY AFTERNOON. GUIDANCE SHOWS A SHORTWAVE

MOVING ACROSS THE IA/SD/NE BORDER EARLY MONDAY MORNING...WITH THE

BEST H850 THETA_E ADVECTION ACROSS THE IA/MN BORDER. THESE LINGERING

THUNDERSTORMS SHOULD BE ELEVATED...WITH MINIMAL THREAT FOR SEVERE

WEATHER...ALTHOUGH A STRAY WIND OR HAIL REPORT IS POSSIBLE. HAVE

HIGHEST POPS ACROSS THE NORTH TO REFLECT THE NORTHERN TRACK

SUPPORTED IN BY THE QPF PLACEMENT IN THE 19.12Z GFS..ECMWF..AND NAM.

HOWEVER...EXPANDED POPS ACROSS THE ENTIRE CWA TO ACCOUNT FOR THE

CONVECTION THAT IS EXPECTED TO BREAK OUT ACROSS NEBRASKA SUNDAY

EVENING...AND MAY STILL BE AROUND BY THE START OF THE PERIOD.

THROUGHOUT THE REST OF THE MORNING HOURS AND INTO EARLY MONDAY

AFTERNOON...THE UPPER LEVEL PV ANOMALY ACROSS THE TX/OK PANHANDLES

SHOULD CONGEAL AN TAKE ON A NEGATIVE TILT AS THE JET STREAK ROUNDS

THE BASE OF THE TROUGH. ANY RESIDUAL CLOUD COVER FROM THE OVERNIGHT

CONVECTION SHOULD QUICKLY DISSIPATE...AND WARM AIR ADVECTION WITH

H700 TEMPS OF 14-16C WILL ESTABLISH A CAP ACROSS CWA. AN ELEVATED

MIXED LAYER FROM 700-500MB...COMBINED WITH AFTERNOON CLEARING SHOULD

ALLOW THE BOUNDARY LAYER TO RAPIDLY DESTABILIZE WITH SBCAPES OF

3000-4000J/KG IN PLACE BY LATE AFTERNOON. THIS CONDITIONAL

INSTABILITY WILL LIKELY BE REALIZED BY LATE AFTERNOON/EARLY EVENING

AS THE STRONG SYNOPTIC FORCING WITH THE HEIGHT FALLS AHEAD OF THE PV

ANOMALY WILL DYNAMICALLY DESTABILIZE THE MID LEVELS AND ERODE THE

CAP. GIVEN THE FAVORABLE THERMODYNAMIC ENVIRONMENT IN

PLACE...ATTENTION THEN TURNS TO THE WIND PROFILE TO DIAGNOSE THE

CONVECTIVE MODE. BY MONDAY AFTERNOON THE AFOREMENTIONED JET STREAK

WILL BE SURGING NORTHWARD ACROSS CENTRAL KS...EASTERN NE. DEEP LAYER

SHEAR VALUES OF 50-60KTS WILL SUPPORT SUPERCELLS. MEANWHILE 6HR

PRESSURE FALLS OVER EASTERN NE/SD WILL RESULT IN SOUTH SOUTHEASTERLY

SURFACE WINDS. SOUNDINGS SHOWS VEERING WIND PROFILE IN THE LOWER

LEVELS FAVORABLE FOR TORNADOES GIVEN THAT THE STORMS WILL BE SURFACE

BASED. THE HIGHEST SHR VALUES WILL BE ALONG THE WARM FRONT...WHICH

SHOULD BE LOCATED ACROSS THE NORTHERN HALF OF IOWA BY LATE

AFTERNOON.

CURRENTLY ENVISION THE SCENARIO UNFOLDING WITH THE WARM FRONT

LIFTING ACROSS THE I80 CORRIDOR BY 18Z...HWY20 BY 21Z...AND TOWARD

HWY18 BY 24Z. GIVEN THE MODEL TRENDS WHICH HAVE INTENSIFIED THE

SYSTEM SLIGHTLY AND SLOWED IT DOWN...DONT SEE THE WARM FRONT SURGING

NORTHWARD INTO MINNESOTA. ALONG THAT SAME LINE OF THOUGHT...FEEL

THAT THE CAP WILL MOST LIKELY HOLD UNTIL AT LEAST 21Z...WITH

CONVECTION BREAKING OUT IN THE AREA OF ENHANCED CONVERGENCE ALONG

THE WARM FRONT. THESE STORMS ARE EXPECTED TO BE SUPERCELLULAR AND

COULD QUICKLY TURN SEVERE. MEANWHILE ANOTHER ROUND OF STORMS SHOULD

DEVELOP CLOSER TO THE UPPER LEVEL DYNAMICS ALONG THE DRY LINE IN

EASTERN NE/KS...AND MOVE THROUGH CENTRAL IOWA OVERNIGHT. THESE

STORMS WILL INITIATE AS DISCRETE SUPERCELLS...AND LIKELY GROW

UPSCALE INTO A LINEAR COMPLEX WITH EMBEDDED HP SUPERCELLS. THE

SEVERE THREAT MAY LAST THROUGH THE EARLY MORNING HOURS OF TUESDAY.

ON TUESDAY...THE CLOSED UPPER LEVEL LOW WILL BE SLOW TO MOVE

NORTHEAST...MEANING THE DYNAMICS WILL STILL BE IN PLACE FOR

ORGANIZED CONVECTION. DEPENDING ON THE AMOUNT OF HEATING THAT TAKES

PLACE...BUFKIT SOUNDINGS FROM WATERLOO SHOW SKINNY CAPE WITH VEERING

WIND PROFILES INDICATING THE POTENTIAL OF LOW TOP SUPERCELLS

DEVELOPING OVER THE NORTHEASTERN PART OF THE CWA DURING THE

AFTERNOON. LOW LEVEL HODOGRAPHS WOULD SUPPORT THE POSSIBILITY OF A

FEW TORNADOES.

22Z Smart Severe Analysis showing highest threat areas in and near Manhattan, KS to Imperial, NE to Topeka, KS to Concordia, KS. Values in this area SFC CAPE 3400 j/kg, LI's -10, 0-1KM SRH 350 m/s, 0-3KM Shear around 50 knots. Right now I have Imperial, NE with the highest chances of tornado potential, with a 92% on the TI index. Outside of this seeing potential convective gusts 81knots, and hail potential of up to 1.8" in diameter. More detailed city analysis has been uploaded. http://smartwxmodel.net
