What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Quad Cities, IA wrote its last area forecast discussion before this red flag warning went out at Mar 7, 3:29 AM CST, 3 minutes earlier.

Area forecast discussion, Mar 7, 3:29 AM CST, 3 minutes before
Area Forecast Discussion
National Weather Service Quad Cities IA IL
329 AM CST Tue Mar 7 2017

.SYNOPSIS...
Issued at 300 AM CST Tue Mar 7 2017

Thunderstorms that brought widespread severe weather to the area
last evening pushed east during the early morning hours. A
westerly wind continued to gust over 30 mph in many locations,
transporting drier and cooler air into the region. Early morning
temperatures ranged from the upper 30s near Independence Iowa, to
the low 50s in western Illinois.

&&

.SHORT TERM...(Today and Tonight)
ISSUED AT 300 AM CST Tue Mar 7 2017

The main forecast issues in the short term period are continued
strong winds today, isolated late afternoon/evening thunderstorms,
and fire weather concerns.

Clouds will clear out quickly this morning with a much drier and
cooler airmass filtering into the region. Upstream obs and a deep
mixed layer on Bufr soundings indicate sustained wind speeds at
or above 30 mph from late morning through the afternoon, as well
as gusts to 45 mph. Have opted for a wind advisory for the
northern 2 tiers for starters. This may have to be expanded
farther south. The 500 mb cold pool with steep mid level lapse
rates will move across the north late this afternoon and evening,
and have included a low pop for showers and thunderstorms through
mid evening. The strong winds and low humidity will dry out the
ground quickly and create ideal conditions for rapidly spreading
grass fires. See fire weather section below.

.LONG TERM...(Wednesday through Monday)
ISSUED AT 300 AM CST Tue Mar 7 2017

Windy conditions for Wednesday along with a very high risk of grass
fires. Refer to the fire weather section for more information.

Windy, dry, and slightly cooler conditions will be seen across the
area on Wednesday. Winds are expected to gust up to 40 mph.

Quiet and dry conditions will be seen Wednesday night through
Thursday night as high pressure moves through the Midwest.
Temperatures will be cooler but still average above normal.

Friday on...

The quiet and dry conditions will continue on Friday. Temperatures
will be a little cooler but still a bit above average. Attention
then turns to the storm systems for the weekend and early next week.

The first of two storm systems will move through the Midwest Friday
night into Saturday. There continues to be considerable differences
among the global models on where this storm will track. The CMC
global has the system passing well to the south of the area. The
ECMWF has the system catching the southern half of the area while
the GFS brings significant precipitation to the entire area. The
possibility does exist that the system could track further to the
south. Everything will depend upon the strength of the cold Canadian
high over the upper Midwest and Great Lakes.

Right now the model consensus has chance to categorical pops Friday
night and Saturday with precipitation ending Saturday afternoon.
Atmospheric thermal profiles will be important for precipitation
type but it appears that rain will change over to all snow Friday
night that continues into Saturday.

Saturday night into Sunday the model consensus has dry conditions as
high pressure quickly moves through the Midwest. Attention then
turns to the next storm system.

Sunday night into Monday a clipper type system will move through the
Midwest. Like the previous system, the global models disagree on the
overall track and timing of the storm system. There seems to be a
loose agreement that the center of the storm system will move across
southern Wisconsin. However, depending upon where the first storm
tracks, the second storm could track further to the south. Right now
the model consensus has chance pops Sunday night with chance to
likely pops on Monday.

Like the first storm, atmospheric thermal profiles will be important
for precipitation type. It appears that the precipitation will start
out as snow Sunday night and change over to all rain during the day
on Monday.

&&

.AVIATION...(For the 06Z TAFS through 06Z Tuesday Night)
ISSUED AT 1123 PM CST Mon Mar 6 2017

VFR conditions for the next 24 hours as storms have moved east as of
07/06Z as cold front passes with fair skies and breezy westerly winds
of 20 to 30+ MPH as high pressure moves in.

&&

.FIRE WEATHER...
Issued at 300 AM CST Tue Mar 7 2017

Grassland Fire Danger Index values will be in the very high to
extreme category for today and Wednesday.

Dry vegetation combined with low humidity values and windy
conditions will result in a very high risk of grass fires today and
Wednesday. The strong winds will dry out the ground from what
rainfall that occurred Tuesday night.

Winds today are expected to gust up to 45 mph and up to 40 mph on
Wednesday. Minimum relative humidity levels today are forecast to be
25 to 35 percent, and 25 to 30 percent on Wednesday.

A Red Flag Warning will be issued for today for the entire area.
No fire weather headlines are planned for Wednesday. However, if
forecast trends over the next 24 hours indicate stronger winds and
lower humidity levels, fire weather headlines may be needed.

&&

.HYDROLOGY...
Issued at 300 AM CST Tue Mar 7 2017

Mississippi River...

The crest on the Mississippi is between L&D 16 and Muscatine.

Muscatine is near crest while areas downstream continue to slowly
rise.

The fast storm movement from last evening produced widespread rain
of 0.25 to 0.3 inches. Localized areas saw rainfall amounts between
1 and 1.5 inches. This amount of rainfall should have minimal effect
on crest forecasts downstream of Muscatine.

This Hazardous Weather Outlook is for portions of north central
Illinois...northwest Illinois...west central Illinois...east
central Iowa...northeast Iowa...southeast Iowa and northeast
Missouri.

.DAY ONE...TODAY AND TONIGHT

Light precipitation and increasing low level moisture will help
to limit the fire weather threat today. However, a south wind
gusting near 40 mph and abundant dry fuels suggest any grass fires
that do develop would spread rapidly.

Isolated thunderstorms are possible this afternoon, with
widespread thunderstorms this evening. Expect scattered severe
storms, with the highest risk between 7 pm and midnight. The
primary threats are damaging winds around 70 mph and isolated
tornadoes. The secondary threat is hail up to quarter size.

Minor flooding is occurring or forecast on portions of the
Mississippi River. Please see the latest Flood Statements and
Flood Warnings for details.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

Winds will gust up to 45 mph Tuesday and up to 40 mph on Wednesday.

The strong winds combined with low humidity levels will result in a
very high risk of uncontrolled grass fires Tuesday and Wednesday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed between 7 pm and midnight
tonight.
