DISCUSSION
ISSUED AT 110 PM CDT FRI APR 3 2026
LARGE AND BROAD TROUGHING TAKES UP MUCH OF THE WESTERN 2/3RDS OF
THE CONUS THIS AFTERNOON WITH A PINWHEEL CLOSED LOW OVER SOUTH
DAKOTA. THE MOMENTUM OF THIS TROUGH CONTINUES TO TAKE IT TO THE
EAST AND A COLD FRONT IS STARTING TO SLOWLY MAKE ITS WAY ACROSS
THE CENTRAL PLAINS. CLOSER TO HOME MODERATE WARM-AIR AND
MOISTURE ADVECTION IS LEADING TO A SLOWLY SCATTERING STRATUS TO
STRATOCUMULUS DECK WITH TEMPERATURES WARMING INTO THE UPPER 70S
AND DEWPOINTS INTO THE MIDDLE 60S. A FEW SHOWERS HAVE TRIED TO
SPARK OFF AMID THIS INCREASINGLY WARM AND MOIST AIRMASS BUT THE
LOW LEVEL LAPSE RATES AND THERMODYNAMICS LOOK TOO MARGINAL FOR
THEM TO BUILD MUCH BEYOND ISOLATED TO WIDELY SCATTERED.
A MUCH BETTER CHANCE OF RAIN IS FORECAST FOR IN THE MORNING AS
THE MAIN COLD FRONT APPROACHES. INSTABILITY NEVER GETS TOO
IMPRESSIVE WITH POOR MID AND LOW LEVEL LAPSE RATES BUT ISOLATED
TO SCATTERED THUNDERSTORMS STILL APPEAR POSSIBLE MID 500-1000
J/KG OF ML/MUCAPE. PWATS INCREASE TO AROUND 1.6 TO 1.7 WITH A
FAIRLY LARGE WARM CLOUD LAYER DEPTH SO HIGH PRECIP EFFICIENCY
LOOKS LIKELY AND A QUICK INCH OR SO OF RAIN LOOKS ENTIRELY
POSSIBLE.
THE COLDER AIR MOVING IN BEHIND THE SYSTEM PUT US BACK CLOSER TO
SEASONAL NORMS WITH HIGHS IN THE 60S AND LOWS IN THE 40S FOR A
FEW DAYS. BY LATE NEXT WEEK CONDITIONS WARM UP AMID DRY WEATHER
AS SURFACE HIGH PRESSURE SETS UP TO OUR SOUTHEAST.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
ISSUED AT 1223 PM CDT FRI APR 3 2026
A CLOUD DECK AT 2500 TO 3500 FT SHOULD START TO SCATTER OUT AT
LEAST A LITTLE SHORTLY, AND THE ODDS FAVOR CLOUD BASES ABOVE
3000 FT REGARDLESS AT MOST SITES WITHIN THE NEXT HOUR OR TWO.
TONIGHT AN AREA OF RAIN WITH EMBEDDED THUNDERSTORMS WILL
APPROACH FROM THE WEST AND TRAVERSE THE REGION THROUGH THE EARLY
TO MID MORNING HOURS. LIGHT RAIN AND MVFR CEILINGS ARE
EXPECTED BEHIND THE ACTIVITY WITH WINDS SHIFTING MORE WESTERLY.
