1059 AM CDT Sat Apr 20 2019

.UPDATE...
1056 AM CDT

Very dry conditions in place per morning upper air soundings and
amdar data, which depict a sharp drop off in dewpoints above the
near surface layer, and mixing is supporting lower dewpoints that
guidance would suggest, and this would create an elevated fire
danger. Expect winds to remain elevated through early afternoon
before a more significant drop off late this afternoon and evening
when the surface ridge will shift overhead.

.SHORT TERM...
330 AM CDT

Through Sunday...

No significant weather concerns in the short term. Gusty northerly
winds are likely today, especially over the eastern CWA where
gusts over 30 mph are possible later this morning into the early
afternoon. As cyclone moves east today will probably see winds
begin to ease slightly later this afternoon. In addition, will
probably see a more traditional lake breeze develop this afternoon
with somewhat lighter winds behind the lake breeze and falling
temps. Near the lake, likely see temps in the mid to upper 40s
most of the day. Big warm up still on tap for Sunday with highs
well into the 70s and perhaps making a run at 80 over north
central IL.

.LONG TERM...
211 AM CDT

Sunday night through Friday...

The warm conditions on Sunday will continue on Monday as
temperatures are likely to top out well into the 70s area-wide.
However, in spite of the mild conditions on Monday, the weather
will become a little more unsettled across the Upper Midwest into
the western Great Lakes region by Monday in response to the next
area of low pressure expected to shift across the Mid and upper
Mississippi Valley. Because of this, there will be a bit more
cloud cover and some chances for showers and thunderstorms later
in the day and into Monday night. It does, however, appear that
the best chance of precip during the day Monday may remain north
of the area.

A cold front is likely to drop southward over the area following
the passage of this surface low on Tuesday. Shower and
thunderstorm chances will continue in the vicinity of this front
on Tuesday, which may set up over central IL and IN later in the
day. North of this boundary cooler weather (low 60s inland) can be
expected Tuesday, with the coolest conditions (low to mid 50s)
likely near the lake due to onshore flow.

By mid to late week, conditions should be mainly dry across much
of the area, with seasonable temperatures in the 60s (warmest
inland). However, the prospects of continued periods of onshore
flow through the week will result in cooler weather near Lake
Michigan.

.FIRE WEATHER...335 AM CDT

Very dry conditions with deep mixing should result in min RH
values dropping below 25% over about the western 2/3rd of the
CWA. Farther east, look strong northerly winds, but somewhat
higher RH values, so for the most part the stronger winds look to
not overlap the area of strongest winds. Area-wide, fuel stick
moisture values are forecast to be above red flag criteria (well
above over the eastern half of the CWA, so while there will be
some heightened level of fire danger, it would appear the threat
of reaching red flag criteria is quite low.

.AVIATION...
For the 12Z TAFs...

Only weather related item of note is the wind. LLWS threat will
subside as gustiness develops again this morning. Winds will
probably begin to slowly ease later this afternoon with winds
quickly going calm or light/variable this evening.
