10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.

Short term (through late Tuesday afternoon)
issued at 325 pm cst Mon nov 19 2018
a weak cold front as of 2000 utc was located near a kmci>>kirk>>kmke
line moving to the southeast. This front will pass through the area
tonight dry due to weak moisture return and low-level convergence
along the boundary. A colder airmass will be ushered in however as
850-hpa temperatures drop back into the -3 to -7c range. As a result
of this strong low-level cold air advection late tonight, low
temperatures are expected to be a bit cooler than this morning. Look
for lows to fall into the 20s to near 30 degrees or about 5-10
degrees below normal for the date. These forecast low temperatures
were generally near or even slightly above the warmer mav guidance
for tonight due to anticipated stratus behind this front.

While sky cover should decrease through the morning hours on
Tuesday, the combination of continued cold air advection at lower
levels of the atmosphere and limited mixing should yield another
cold day for the middle of november. High temperatures in the upper
30s to to low 40s are forecast, which largely is between the warmer
mav and cooler met guidance.

Long term (Tuesday night through next Monday)
issued at 325 pm cst Mon nov 19 2018
(Tuesday night - Thursday night)
quiet and dry weather is favored for the Tuesday night through
Thursday night time period as surface high pressure slowly slides
from the upper mississippi river valley off toward the great lakes.

Temperatures are forecast to remain on the cool side relative to
normal at night (mid 20s to low 30s), but daytime highs should
moderate back into the 50s which is right around normal for the
middle of november.

(Friday - next Monday)
two systems will affect the forecast area during this time period as
the weather pattern becomes more active once again. The first system
is expected to bring a round of rain to the area Friday through
Friday night. Models are in fairly good agreement with this first
system, both in terms of timing and track of the upper-level
disturbance.

More uncertainty lies with the second system which looks to bring
another round of precipitation to the region Sunday into next
Monday. Deterministic guidance is highly variable with the specifics
of this system (track timing strength), but general consensus is for
an area of low pressure to develop along a southwest-northeast
oriented baroclinic zone and track to the east northeast across the
mid-mississippi valley. While there will not be sufficiently cold
air in place out ahead of this system for anything but liquid rain,
there is the possibility for the rain to mix with or change over to
snow before ending as the low moves into the ohio valley. At this
early juncture, rain changing to snow would be more likely across
far northern sections of the forecast area based on the track of the
surface cyclone.

Temperatures on Friday and Saturday will start off near normal as
high temperatures rise into the 50s each day with lows in the
30s 40s Saturday morning. A return to below normal temperatures day
and night is then favored for Sunday and next Monday as colder air
filters into the mid-mississippi valley behind the departing area of
low pressure.

Aviation (for the 06z tafs through 06z Tuesday night)
issued at 1048 pm cst Mon nov 19 2018
cold front was moving southeastward through the st. Louis metro
area late this evening. Post frontal stratus clouds around 1700
to 2000 feet in height will advect into cou and the st louis metro
area overnight. Surface wind will become northwesterly and
increase to around 10 kts in the st louis metro area after fropa.

The MVFR clouds will advect southeast of the TAF sites by late
Tuesday morning. The northwest surface wind will back around to a
southwest direction by late Tuesday afternoon as the surface ridge
over the plains moves southeastward into southern portions of mo
and il.

Specifics for kstl: cold front has just passed southeast of stl
late this evening with the surface wind becoming northwesterly
and increasing to 10 kts after fropa. Post frontal stratus clouds
around 1700 to 2000 feet in height will advect into stl overnight.

The MVFR clouds will advect southeast of the stl area late
Tuesday morning. The northwest surface wind will back around to a
southwest direction late Tuesday afternoon as the surface ridge
over the plains moves southeastward into southern portions of mo
and il.

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.
