 A freeze warning is in
effect from 3 to 8 a.m. Wednesday for the counties of Knox, Stark,
Peoria, Marshall, Woodford, Fulton, Tazewell, McLean, Schuyler,
Mason, Logan, DeWitt, Piatt, Champaign, Vermilion, Cass, Menard,
Scott, Morgan, Sangamon, Christian, Macon, Moultrie, Douglas, Coles,
Edgar, Shelby, Cumberland, Clark, Effingham, Jasper, Crawford, Clay,
Richland and Lawrence, including the cities of Galesburg, Peoria,
Bloomington, Normal, Havana, Lincoln, Champaign, Urbana, Danville,
Jacksonville, Springfield, Taylorville, Decatur, Charleston,

Temperatures: Expect lows tonight to range from 29 to 32
degrees.
Impacts: The cold temperatures may damage sensitive outdoor
plants.
Precautionary, preparedness actions: A freeze warning means
subfreezing temperatures are imminent or highly likely. These
conditions may kill crops and other sensitive vegetation. If
possible, bring plants indoors or cover those that will remain
outside overnight.

In addition, outdoor burning is discouraged today.
A special related statement was released by the National Weather
Service at 3:36 a.m. Tuesday for the counties of Knox, Stark,
Peoria, Marshall, Woodford, Fulton, Tazewell, McLean, Schuyler,
Mason, Logan, DeWitt, Piatt, Champaign, Vermilion, Cass, Menard,
Scott, Morgan, Sangamon, Christian, Macon, Moultrie, Douglas, Coles,
Edgar, Shelby, Cumberland, Clark, Effingham, Jasper, Crawford, Clay,
Richland and Lawrence, including the cities of Galesburg, Peoria,
Bloomington, Normal, Havana, Lincoln, Champaign, Urbana, Danville,
Jacksonville, Springfield, Taylorville, Decatur, Charleston,
Mattoon, Shelbyville, Effingham, Flora and Lawrenceville.
According to the statement, high pressure at the surface and
continued northwesterly flow are keeping central Illinois very dry
at the surface. Minimum relative humidity values are expected to
fall into the 20-25 percent range this afternoon. Ten-hour fuels are
ample across the region as well. Both conditions are indicative of
issues for fire weather interests. However, sustained winds are
expected to remain just below the criteria for a “red
flag warning.” With anticipated deeper
diurnal mixing, gusts to 30 mph will be possible later in the
afternoon.
Burning in central Illinois today would be ill-advised, and fire
weather concerns should remain alert for potential issues with any
attempted burn this afternoon and be aware that conditions could
change rapidly.

 In
a summary weather outlook, at 6 a.m. Tuesday the NWS released a
freeze warning in effect from 3 to 8 a.m. Wednesday for the counties of Cass, Champaign, Christian,
Clark, Clay, Coles, Crawford, Cumberland, DeWitt, Douglas, Edgar,
Effingham, Fulton, Jasper, Knox, Lawrence, Logan, Macon, Marshall,
Mason, McLean, Menard, Morgan, Moultrie, Peoria, Piatt, Richland,
Sangamon, Schuyler, Scott, Shelby, Stark, Tazewell, Vermilion and
Woodford.
The following weather outlook is for portions of central,
east-central and southeast Illinois.
Tuesday and Tuesday night
Low temperatures will reach 29 to 32 degrees tonight. These
temperatures may harm tender vegetation that cannot be covered or
brought indoors.
Outdoor burning is discouraged today. Northwest winds of 15 to 25
mph will combine with dry vegetation and low humidity to create
conditions favorable for the spread of fires. Even small, attended
fires may quickly spread out of control due to blowing embers.
Wednesday through Monday
Subfreezing temperatures will be likely again Wednesday night
over most of the area, with east-central Illinois seeing the lowest
temperatures.
The chances for thunderstorms will increase beginning Friday and
will continue into early next week as an upper-level storm and
associated cold front move into the Midwest and stall. Increasing
amounts of moisture will come northward from the Gulf of Mexico
through the Mississippi Valley, so the potential will exist for
occasional heavy rain or severe storms.
Keep informed of later forecasts as the situation becomes better
