RIDGE OF HIGH PRESSURE STRETCHED ACROSS THE NORTHERN PLAINS AND INTO
NORTHEAST IOWA THIS MORNING. THE RIDGE WILL SHIFT NORTHEAST DURING
THE DAY AS LOW PRESSURE ON THE LEE SIDE OF THE ROCKIES DEVELOPS.
THETA-E ADVECTION WILL BE TAKING ACROSS SOUTHERN IOWA MUCH OF THE
DAY BEFORE LIFTING OVER THE NORTHERN PORTION OF THE STATE THIS
AFTERNOON. THIS WILL RESULT IN A MORE DENSE AND LOWERING CLOUD
SHIELD. IT IS POSSIBLE A SHOWER OR TWO WILL REACH THE FAR SOUTHWEST
COUNTIES AFTER 21Z. TEMPERATURES WILL BE LIMITED OVER THE SOUTH DUE
TO CLOUD COVER WHILE SOME SUN IS EXPECTED OVER THE CENTRAL AND NORTH
THIS MORNING DESPITE PASSING MID LEVEL CLOUDS.

.LONG TERM /TONIGHT THROUGH WEDNESDAY/...MAIN FOCUS OF THE FORECAST
WAS WITH POTENTIAL WINTER STORM ACROSS NORTHERN IOWA TONIGHT THROUGH
MONDAY. MODELS ARE IN GOOD AGREEMENT OVERALL WITH THIS SYSTEM...WITH
THE NAM SLIGHTLY FURTHER SOUTH THAN THE SREF/GFS/ECMWF AND LEFT THE
NAM OUT.

TONIGHT THROUGH MONDAY...WELL ADVERTISED STRONG WAA ALOFT AND
ISENTROPIC LIFT DEVELOPS TONIGHT INTO SUNDAY MORNING AHEAD OF THE
SURFACE LOW. LLJ INCREASES TO TO 40-50KTS AT 850MB WITH TEMPS
RANGING FROM 0C ALONG THE IA/MN BORDER TO +9C ACROSS THE SOUTH.
VERY STRONG FRONTOGENETICAL FORCING BETWEEN 850-700MB LINES UP ALONG
NORTHERN IOWA/SOUTHERN MINNESOTA. FORECAST SOUNDINGS JUMP RIDE
ALONG THE 0C OVERNIGHT TONIGHT INTO TOMORROW MORNING BEFORE THE
LARGE WARM LAYER ALOFT IS MORE EVIDENT BY AROUND 15Z SUNDAY. SREF

KEEP SURFACE TEMPS ACROSS THE NORTH AROUND FREEZING. THE SURFACE LOW
LOOKS TO TRACK ACROSS SOUTHEAST NEBRASKA INTO SOUTHERN IOWA TONIGHT
INTO SUNDAY...WITH THE WARM SECTOR ROUGHLY ALONG AND SOUTH OF
INTERSTATE 80. THERE IS SOME ELEVATED INSTABILITY WITH THE WARM
FRONT TONIGHT AND KEPT WITH MENTION OF THUNDER OVER THE SOUTH.

DRY SLOT PUNCHES INTO SOUTHWEST IOWA BY SUNDAY AFTERNOON AND
EVENING...AND DECREASED POPS ACROSS THE AREA DURING THIS TIME. WRAP
AROUND MOISTURE AND COLDER TEMPS WILL LEAD TO ALL SNOW BY 00Z MONDAY
ACROSS THE NORTHEAST...WITH STILL A MIX OVER THE EASTERN EDGES OF

AMOUNTS LOOK TO RANGE UNDER 4 INCHES ACROSS THE NORTH...BUT WITH THE
AMOUNT OF ICE ANTICIPATED...FELT A WINTER STORM WARNING IN THE
NORTHEAST WAS WARRANTED. QUESTIONABLE HOW MUCH ICE WILL MELT...IF
ANY AT ALL IF SURFACE TEMPS WARM ABOVE FREEZING SUNDAY AFTERNOON.
CAA CONTINUES THROUGH THE DAY MONDAY WITH AN ADDITIONAL INCH
POSSIBLE OVER THE NORTHEAST FORECAST AREA BY THE AFTERNOON.

TUESDAY AND WEDNESDAY...SURFACE HIGH PRESSURE WILL BUILD INTO THE

TEMPERATURE. HAVE TRENDED MORE RAIN AT KALO WITH THIS FORECAST.

&&

RECENT WARM WEATHER AND SNOW MELT RUNOFF WILL CONTINUE TO HELP BREAK
UP ICE ALONG AREA RIVERS AND STREAMS THROUGH THE WEEKEND. THE THREAT
FOR ICE JAMS WILL CONTINUE THROUGH THE PERIOD WITH THE POTENTIAL FOR
FLASH FLOODING AS WATER BACKS UP AND RISES RAPIDLY BEHIND THESE

PASSAGES ALONG STREAMS WHERE ICE CAN BECOME HUNG UP. AN ICE JAM IS
CURRENTLY AFFECTING THE FORT DODGE AREA ALONG THE DES MOINES BASIN.
