Weather Summary for Iowa
National Weather Service Des Moines IA
306 AM CDT Mon May 27 2019

A large pocket of showers, with a few rumbles of thunder, moved across
central to northern Iowa shortly after midnight this morning. 
Rainfall amounts with this precipitation were generally in the one- 
quarter to one-half of an inch range. Meanwhile, a line of strong to 
severe storms has been pushing east to northeast throughout the early 
morning hours. Salina, Kansas had a measured wind report of 76 miles 
per hour with this line. This line will be impacting northern Missouri
and possibly southern to southwestern Iowa by sunrise this morning. 
Additional showers and storms will be surging ahead and impacting 
western to northern Iowa by sunrise as well. Severe weather is not 
expected with this line, however, heavy rainfall may lead to flooding 
concerns in already rain-soaked areas.

Temperatures during the morning hours were slightly warmer than they
have been the past few morning's as temperatures were generally 
within a few degrees on either side of 65 degrees. Normal low 
temperatures for this time of year are in the low to mid 50s, placing 
temperatures for this morning around 10 degrees above normal. Winds 
were generally from the east to southeast at around 5 to 10 mph, with 
occasional gusts around 15 to 20 mph.

For the rest of today, expect rain to continue across much of the
state. Strong to severe thunderstorms are possible, especially in
central to southern Iowa. For Tuesday, strong to severe thunderstorms
are possible once again. Temperatures should be in the 70s, with lows
in the 50s to 60s.

Hazardous Weather Outlook For HENRY County,IA

355 AM CDT Mon May 27 2019

 DAY ONE  MONDAY AND MONDAY NIGHT

Severe storms are possible across the area today through this
evening and the Storm Prediction Center has an enhanced risk over
much of east central Iowa and all of northwest Illinois. There is
a slight risk over the remainder of the outlook area. Storms with
the potential for strong winds and heavy rainfall will move into
the area this morning. 

A greater risk for severe storms will occur this afternoon as a 
warm front lifts northward across the area. Thunderstorms are
likely with a few supercells possible, especially in the afternoon.
The severe weather threats will include damaging winds, large 
hail and tornadoes. Scattered storms will be possible in the 
evening, with a few possibly severe before 10 pm. 

Heavy rainfall will be possible today through the evening hours. 
This may lead to flash flooding as soil conditions are saturated 
from the recent wet weather.

Area rivers are experiencing flooding. Please see the           
latest Flood Statements and Flood Warnings for details.

 DAYS TWO THROUGH SEVEN  TUESDAY THROUGH SUNDAY

Both severe weather and heavy rain are a threat Tuesday and a 
lesser threat Wednesday. SPC currently has the area in a slight
risk Tuesday and marginal risk Wednesday, reflecting the relative
risk of severe weather each day. Additional rainfall will 
continue to exacerbate flooding on both the Mississippi River and 
tributaries.

Another round of storms is forecast late Friday night into
Saturday, and rain could linger intermittently through the
weekend. While it is too early to predict any severe weather
hazards, additional rainfall would continue to maintain high soil
moisture levels and flooding on area rivers.

 SPOTTER INFORMATION STATEMENT  
Spotter activation and amateur radio activation may be needed this
afternoon and evening.
