Update
Issued at 1034 am cst Mon feb 19 2018
showers storms becoming a little less widespread across central
and southeast illinois as an upper-level short wave lifts off to
the northeast and the low-level jet weakens. This lull (although
not everywhere has seen a lull yet) should last until mid-
afternoon. Then, another short wave, which is racing northeast
from the southern plains, will begin to push into the region and
bring the next more widespread round of precipitation.

Updated forecast for latest the latest hourly trends into this
evening, primarily to adjust pops.

Short term (today and tonight)
issued at 345 am cst Mon feb 19 2018
an amplified upper level flow regime across the country will
prevail during the upcoming week, and keep central and southeast
il in a very moist SW flow with several chances of moderate to
heavy rain. Will see a growing threat for flooding as the week
progresses, therefore will reissue the esf product to cover this
potential developing flood situation during this week.

Radar mosaic shows scattered showers and isolated thunderstorms
south of macomb to rantoul line at 330 am and were tracking
quickly ne. This convection caused by a warm front lifting
northward across central il and precipitable water values rising
to 1-1.25 inches. Breezy sse winds of 8-18 mph and some gusts to
around 25 mph have been causing temperatures to slowly rise during
the night. Current mercury levels range from 41f at galesburg and
lacon, to lower 50s along and south of a pittsfield to effingham
to terre haute line. Breezy south winds 15-25 mph and gusts of
25-35 mph today to bring unseasonably mild air today with highs in
the 60s, warmest from springfield and robinson SW where upper 60s
to near 70f.

Latest forecast models shows 999 mb surface low pressure over ne
ks ejecting NE into NW il by early this evening, and into the
western great lakes by dawn Tue while pushing cold front toward
the ia il border. Very moist air mass spreading over CWA today as
precipitable water values peak around 1.50 inches across heart of
cwa during the day. This will continue periods of showers and
isolated thunderstorms spreading NE over much of CWA especially
from i-70 north today and tonight. Rainfall amounts range from
three quarter to 1.5 inches along and north of i-70 through
sunrise Tuesday. Unseasonably mild lows tonight in the upper 50s
and lower 60s, except near 50f far NW CWA by galesburg.

Long term (Tuesday through Sunday)
issued at 345 am cst Mon feb 19 2018
00z forecast models have trended a bit quicker with pushing strong
cold front SE through the il river valley during Tue afternoon and
thru rest of central il during Tue evening, and into southeast il
overnight Tue night, approaching the ohio river by dawn wed.

Heaviest rainfall over the il river valley Tue afternoon, shifts
into central il Tue evening and into southeast il overnight tue
night. Another 1-2 inches of rain expected from Tue through wed
morning across cwa, with 2-2.5 inches SE of i-55. This time frame
it the most vulnerable for flooding over central and southeast il
from Tue afternoon through Tue night, and continue over southeast
il into wed. A flood watch may eventually be needed during this
time frame. Highs Tue contrast from upper 50s by galesburg, to
the lower 70s in southeast il. Rain Tue evening, will change to
freezing rain and sleet late Tue evening at galesburg and spread
into central il during overnight Tue night with around a tenth
inch of ice possible by Wed morning west of a rantoul to decatur
to taylorville line and this area may eventually need a winter
weather advisory. The il river valley dries out briefly on wed
while rain likely continues in southeast il, with mixed pcpn over
central part of CWA Wed morning and mainly light rain wed
afternoon. Highs Wed range from mid 30s over il river valley, to
low to mid 40s in southeast il.

Stayed close to consensus of models for forecast from Thu through
this weekend. Thu and Thu evening appear to be a dry period as
strong high pressure drifts east across the great lakes. But more
rain spreads NE across area during overnight Thu night into fri
and continues through Sat night as a couple waves move NE along
frontal boundary SE of cwa. Mixed pcpn including snow is possible
over NW CWA overnight Thu night into Fri morning and again
overnight Fri night into early Sat morning. Additional rainfall
amounts of 1-2 inches possible south of i-72 late this week with
locally 2-3 inches by lawrenceville. Highs range from 40-50f from
nw to SE on thu, and from 45-55f fri-sun, except upper 50s in
southeast il this weekend.

Aviation (for the 18z tafs through 18z Tuesday afternoon)
issued at 1130 am cst Mon feb 19 2018
MVFR and or ifr condtions will prevail through the 18z TAF valid
time across the central illinois terminals. Most local TAF sites
have climbed to MVFR late this morning due to daytime heating and
the bulk of the heaviest rainfall having pushed off to the
northeast. Expect a return to widespread ifr condtions across the
area tonight as diurnal heating is lost and as rainfall coverage
increases again. Only carried vcts for most of the period.

Thunderstorms will be around, but not too numerous, making
confidence in specific timing location too low to go with
predominant or tempo thunder. Winds off the deck will increase
again tonight, and surface gusts will subside slightly, causing
non-convective llws for most of tonight.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
