Weather Summary

Weather Underground midday recap for Thursday, May 23, 2013.

Severe storms developed over the Southern Plains from northern Texas through northern Oklahoma on Thursday. A trough of low pressure lingered over the region, which pulled moisture and energy in from the Gulf of Mexico. This allowed for showers and thunderstorms to develop in these areas, some of which turned severe with large hail, damaging winds, and periods of heavy rainfall. A brief tornado was reported near Cedar Hill, Texas. Hail 2.5 inches in diameter was reported near Davis, Oklahoma and 65 mph winds were reported at Newcastle and Dickson, Oklahoma. Rainfall totals varied over 2 inches with this system. Oklahoma City reported a mid-day total of 2.92 inches of rain.

Meanwhile in the East, a trough of low pressure over the East Coast allowed for a strong cold front to stretch from the Northeast through the Eastern Valleys. Moisture ahead of this front allowed for showers to develop from the Carolinas through Maine, with some areas of thunderstorms. There was a slight chance that these storms would turn severe from Virginia through New Hampshire, but severe storms have not developed.

Meanwhile Out West, a low pressure system mover the Rockies maintained widespread showers across the Pacific Northwest and Northern Rockies. Strong winds developed ahead of this system from eastern Montana through western Colorado. Gillette, Wyoming reported maximum winds up to 56 mph.

Mobile & Email Alerts Statement as of 8:47 PM CDT on May 23, 2013

... Patchy frost possible tonight...

An unseasonably strong and cool area of high pressure will spread
across the mid and upper Mississippi Valley tonight. The
combination of clear skies and light winds associated with the
high will allow temperatures to drop into the middle to upper 30s
across portions of northern Illinois overnight. Some patchy frost
is possible in some of the colder more sheltered locations by
sunrise Friday... especially in low lying areas. Although widespread
frost is not expected... any frost that does form could result in
damage to sensitive vegetation if left unprotected. Temperatures
will quickly warm after sunrise on Friday... ending the threat

... Lake Michigan Beach forecast season begins may 24th...

The National Weather Service Chicago office will resume issuing
surfzone forecasts for the shoreline of lake and Cook counties in
Illinois and lake and Porter counties in Indiana for the Summer
swim season beginning Friday may 24th.

New for this year: beach hazard statements...

Beach hazard statements will be issued over the Summer on days
when dangerous swimming conditions are expected. The beach hazard
statement addresses various beach hazards and replaces the rip
current statements that have been issued in past years. See the
service change notice at...
www.NWS.NOAA.Gov/om/notification/scn13-33bhs_expansion.Htm for
more details on this transition.

Swim hazard risk replaces rip current risk in the surfzone
forecast...

Part of the transition to beach hazard statements will include the
surfzone forecast. The surfzone forecast will no longer refer to
rip current risk... but instead low... moderate and high swim risk.

Factors contributing to dangerous swimming conditions...

... High waves...

High waves pose several dangers to swimmers at Lake Michigan
beaches. First... high waves will cause swimmers to become
fatigued. Large waves are very powerful and can push a person off
a sandbar and into deeper water... requiring them to swim through
a rapid succession of waves to get back to more shallow water.

... Rip currents and structural currents...

Also... high waves result in strong rip currents and strong
structural currents. Rip currents are strong channels of water that
form rapidly and flow quickly away from shore through breaks or
low spots in The Sandbar. Structural currents are strong currents
which frequently flow along piers... breakwalls... and jetties
toward deeper water offshore.

... Strong offshore winds...

Dangerous swim conditions can also develop with strong offshore
winds. Although wave heights would tend to be lower with offshore
winds... strong winds can still cause dangerous structural currents
in the Chicago area. Southerly winds over 35 mph resulted in
dangerous currents near a pier at Loyola Park beach on may 24
2012... a contributing factor in the tragic drowning of a 15 year
old female.

Furthermore... particularly at the Indiana dunes beaches... strong
southerly winds pose a unique hazard to those on rafts. These
winds can create a current that pulls rafts well away from shore
into deeper water. A 31 year old male drowned on June 18 2012 at
Lake View beach in Beverly Shores when his raft capsized and blew
away from him after drifting over a quarter mile from shore due
to 30 mph southerly winds.

Criteria for issuance of beach hazard statements...

NWS Chicago will issue a beach hazard statement when there is a
high swim risk due to either of the following:

1) high waves of at least 3 to 5 feet and dangerous currents.

2) winds of 30 mph or higher.

We will no longer be issuing statements for a moderate risk... but
a moderate risk will be highlighted in the surfzone forecast.

People heading to Lake Michigan beaches this Summer should...

1. Check www.Weather.Gov/Chicago or NOAA Weather Radio to see if
any beach hazard statements are in effect... and if they are...
plan to stay out of the water on that day.

2. Swim on lifeguarded beaches when possible.

3. Refer to warning flags at local beaches for the latest
information before going into Lake Michigan waters (flag
definitions... green: OK to swim... yellow: caution is urged...
red: hazardous to swim).

Swimming at Lake Michigan beaches is a wonderful part of living
or visiting this area... but on days when waves are high and/or
currents are strong... it is a very dangerous activity and one
that should be postponed until the hazardous conditions subside.
Please stay informed and safe this Summer... and enjoy the
beaches!
