... Flash Flood Watch remains in effect through Saturday morning...
The Flash Flood Watch continues for
* portions of central Iowa... north central Iowa... northeast
Iowa... northwest Iowa and west central Iowa... including the
following areas... in central Iowa... Grundy... Hamilton... Hardin
and Webster. In north central Iowa... Butler... Cerro Gordo...
Franklin... Hancock... Humboldt... Kossuth... Winnebago... Worth
and Wright. In northeast Iowa... Black Hawk and Bremer. In
northwest Iowa... Emmet... Palo Alto and Pocahontas. In west
central Iowa... Calhoun and SAC.
* Through Saturday morning
* ice jams along area rivers and their respective tributaries may
lead to flash flooding. The rivers of concern include... the
Cedar River north of Waterloo... Beaver Creek in and around New
Hartford... the Shell Rock river near and upstream of Shell

Precautionary/preparedness actions...
A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.
Be especially careful if you are out in areas of fog... as you may
not see flooded areas until it is too late.
You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.

NWS Forecaster Discussion
593 fxus63 kdmx 120522 aab afddmx Area forecast discussion...updated National Weather Service Des Moines Iowa 1122 PM CST Thursday Mar 11 2010 ..updated aviation discussion... Short term /tonight/... surface low directly centered over the County Warning Area and will continue to spin across central Iowa tonight into Friday morning. Short term models are in decent agreement for tonight...and leaned toward a blend with the sref/NAM. Low will meander to the northwest through tonight will continue to advect warm moist air into the eastern and northern sections of the County Warning Area. With alo getting into the lower 50s today...temperatures look to stay fairly mild overnight across the east with the warm air advection persisting. Soundings remain saturated across the west to northwest tonight into early Friday...so kept best chance of rain going in this area. Otherwise...more likely to see widespread fog and drizzle with the abundant moisture available in the lower levels. Long term /Friday through Thursday/... low pressure centered over centered northwest Iowa will begin to retrograde back to the south by Friday as southern stream energy once again takes over. As this occurs...the upper level dry slot will move into central Iowa and will keep precipitation chances low over this region. Best chances for precipitation will be over the far west and south. However no significant precipitation is anticipated. Kept precipitation type as rain. Despite 850 mb falling below zero tonight into Friday...low level dewpoints remain above freezing and should help keep a sufficient warm layer for rain. Next significant short wave currently located over central Texas will lift northeast into the middle Ohio Valley by late Friday then wrap up and retrograde west with some qg forcing into southeast Iowa and northern Missouri. Certainly placement issues with this system that could have significant impacts on central Iowa flooding. Currently favor a more southern track with less quantitative precipitation forecast that would not impact expected flood crests. Also...current track would not favor the quantitative precipitation forecast forecast by the 12z NAM/European model (ecmwf) given activity going on to the southeast and Gulf moisture being shut down. General trend for Sunday and beyond is for slow warming at the surface then thermal ridge beginning to lean into the Midwest by Thursday. A little hesitant to raise temperatures to mex guidance given potential for cloud cover. Any breaks in the sun though should help push readings to near 50. Current forecast is dry with lack of middle moisture despite some light returns from long term guidance. && Aviation... 12/06z...surface low will meander over western Iowa overnight before moving southeast across Missouri on Friday. Low clouds and pockets of MVFR fog will affect the area through the night...with the lowest conditions found at kfod closer to the center of the low. Kdsm may also experience a few periods of IFR ceilings...otherwise only MVFR conditions expected at the remaining terminals. Dz will not have much of an effect and other than at kfod MVFR visibilities will be few and far between. Conditions will steadily improve after sunrise as the low begins to slowly move away...but expect MVFR ceilings to continue for most of Friday. && Hydrology... widespread moderate to major flood event continues to unfold across the entire County Warning Area. We/re not looking at another 2008 event however. This flood event was expected to occur...though...per our first Spring flood outlook from late January which highlighted a high risk of significant flooding. The flood threat is migrating from south to north with time. Basins of most concern are first the Des Moines/Raccoon...followed by the Cedar/Iowa then skunk. Moderate to major flooding expected at many locations in the Des Moines/Raccoon river basins. Ice jams continue to be problematic...with the leading edge of the activity migrating from south to north ahead of the overall flood threat. The ice jam activity has been rather predictable for this event...with the majority of the events occurring within 12 to 24 hours after streams begin to rise. The ice jam activity has been more prolific than normal...which was expected. The ice has become thicker than normal...due to our colder than normal winter...with thicknesses exceeding 12 to 18 inches in some locations. The ice jam hot spots today have included but are not limited to The Fort Dodge area...as well as various locations in the Cedar River basin upstream of Waterloo. Due to the widespread potential for flash flooding from the jams...we elected to issue a Flash Flood Watch for counties along and north of U.S. Highway 20. We will have to continue monitoring the next weather system to affect our County Warning Area Friday night into Saturday. Our present river forecasts do include expected rainfall from this system. As the forecasts show...we do not expect the rain to add significantly to the crests like what happened in 2008 in some locations. Regardless of how much rain falls this weekend...however...many streams will be slower than normal to recede Post-crest and fall below stage...as the runoff from snow melt as well as excess soil moisture takes a while to finds their way into the streams. && Dmx watches/warnings/advisories... Flash Flood Watch through Saturday morning for north central Iowa. && $$ Short term...klp long term...donavon aviation...Lee hydrology...zogg
