NWS Twin Cities, MN wrote its last area forecast discussion before this flood watch went out at Oct 7, 1:16 PM CDT, 2 hours 5 minutes earlier.
Area forecast discussion, Oct 7, 1:16 PM CDT, 2 hours 5 minutes before
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 116 PM CDT Sun Oct 7 2018 .SHORT TERM...(Today and tonight) Issued at 400 am CDT Sun Oct 7 2018 High pressure located over southwestern Ontario will drift to the east today and we will continue with another day of clouds and minimal temperature increases. Forecast soundings indicate the layer between 2000 and 3500 feet remaining pretty much saturated, like yesterday. Therefore expect no sunshine today. Moisture and warm air advection will increase this afternoon into tonight in the low levels in response to the deep trough over the Rockies slowly moving toward the high Plains. A scattering of showers will move into the southern part of our forecast area later this afternoon and reach the northern part of the area in the evening as deep southwesterly flow develops aloft. There are some differences in when precipitation arrives as the RAP is a few hours faster than the GFS so went with a compromise. Regardless of the timing differences, this will merely be the start of a significant and prolonged rainfall event, with increased moisture transport with the threat for heavier precipitation arriving late tonight. Overall not a very pleasant day relatively speaking if you intend to be outdoors. .LONG TERM...(Monday through Saturday) Issued at 400 am CDT Sun Oct 7 2018 ...Confidence Increasing On A Period Of Excessive Rainfall... The main forecast concern deals with where the frontal boundary lies late Monday/Tuesday/early Wednesday which will dictate the axis of the heaviest rainfall. There is no doubt that the Upper Midwest will see bouts of rainfall from tonight, through Wednesday morning. Percentages will range from 60 to 100% which is based on timing of the individual short waves riding northeast across the Plains, and into the Upper Midwest. Consistency on where the frontal boundary lies remains a problem with the GFS and the parallel GFS which will become operational in the next 6 months. Both the EC and Canadian models have better consistency on the frontal boundary which also has a narrower axis of where the heaviest rainfall will fall over the next 72 hours. The GFS, and the parallel run remain the outliers and have lifted the frontal boundary further to the west/north. This leads to the heavier axis of rainfall further west than the EC/Canadian depiction. There still remains some uncertainties on where this frontal boundary eventually lines up, which will likely be dictated by convection and the strength of the mean upper ridge off the east coast. Therefore, will continue to forecast that the probability of excessive rainfall in the forecast, but where the heaviest axis lies remains questionable. One of the aspects of the GFS/Parallel GFS, is if the frontal boundary is further to the west/north, the chances of severe weather also increases based on the available instability. CIPS analogs (00Z/07) support a high probability of 2" rainfall totals Between Monday night, and Wednesday morning. There is also a few percentage points of 4 inch totals based on the mean weather parameters of the current operational GFS. The EC mean precipitable water and return interval for this time frame does support a very anomalous high value. Based on climatology (1979-2009), these values (3-4 standard deviation above normal) are rare and usually only happen every 10 to 20 years. Wednesday will be the turning point of when the precipitation will slowly depart, with a few days of dry weather. The mean upper flow continues to support a cold period through the 15th of October. After the 15th of October, there are signs that the mean upper flow will become more zonal, which will lead to a moderation in temperatures. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 115 PM CDT Sun Oct 7 2018 Fairly straight forward TAFs as the beginnings of a prolonged rain event are quickly heading north across Neb/IA. As the rain moves in, cigs will drop down to the IFR level and will remain IFR/LIFR through the period. Visibility forecasts may be a bit pessimistic. The front that is currently down from the MO/IA/IL border over to northern IN/OH will lift northwest overnight and move into southeast MN/central WI Monday. Look for the worst cigs/vis along and ahead of this boundary. Right now, cigs are 003-007 with 2-4sm vis across northern IL and the MI/IN border and this will be up here much of Monday. KMSP...Fairly high confidence in this forecast. It will not rain the entire time tonight/Monday, but with no significant changes in cig/vis conditions in dry periods, didn't try to get cute and time some dry periods in. Something else we'll have to watch out for Monday afternoon is the treat for thunder as the warm front approaches. Kept it out for now, but reflectivity forecasts from the NAM indicate we'll have potential for convection here at the end of this TAF period. /OUTLOOK FOR KMSP/ Tue...IFR/LIFR with RA. Wind NNE 5 kts. Wed...MVFR chc IFR mrng cigs. Wind NW 10G20 kts. Thu...Chc MVFR cigs. Wind NW 10G20 kts. && .HYDROLOGY... Issued at 400 am CDT Sun Oct 7 2018 A very moist airmass with precipitable water values between 1.5 and 1.75 inches will produce periods of relatively heavy rain for October. A stationary front will begin moving toward the area today as a warm front with several disturbances moving through the area during next few days. This will provide us with several periods of potentially heavy rain. Because of an abundance of rainfall earlier this month and in September and the fact that its been so cloudy and cool, soils are very wet and rainfall later tonight will help saturate the soils. We can expect rivers to rise with some flooding possible. Much of our forecast area will see 2-4 inches of rain by Wednesday morning. Some areas across southern and eastern MN extending into western WI may see rainfall amounts in the 4 to 6 inch range depending where the warm front sets up. This rain will cause rises on rivers and streams and will likely lead to flooding in some areas, especially in the corridor of heaviest rainfall. In addition, lowland flooding may also occur as the ground quickly becomes saturated. Keep updated on the latest forecast for any future watches and warnings. && .MPX WATCHES/WARNINGS/ADVISORIES...
