Aviation
Scattered to numerous showers with heavy rain have been steadily
movg nwd across NE tx to SE ok and SW ar. All areal terminals,
except for kmlu and keld, will lie either near or directly in this
swath of heavy rain for the next few hours. Low MVFR to ifr cigs
and vsbys will likely occur in rain, and may continue outside of
rain, with CIGS likely remaining mostly MVFR thru the aftn. Keld
may see current lifr conditions persist thru the mrng hours as
well, as cooler air north of frontal boundary just north of i-20
condenses as lgt NE winds fill in the low lying terminal
location. A few embedded tstms possible this aftn as well.

Widepread ifr conditions expected most of the region in the
overnight hours, expecially were daytime temps fail to reach 80
degrees. 07 .

Prev discussion issued 605 am cdt Sun sep 23 2018
short term... Today through Monday
areas of heavy rain streaming nwd have begun to reorganise with
training cells from the east tx lakes to SE ok SW ar. Flash flood
watch that was in effect until 7 am across SE ok SW ar NE tx and
nw la along and north of i-20, has now been extended until 7 pm
this eve. A few locations have experienced significant flooding
and with rain setting up, could see a repeat today with pcpn water
possibly peaking near 2.5 inches and deep south flow condusive to
cell training. Also expecting possible dense fog overnight across
regions where heavy rain falls and aftn temps remain in the 70s.

Some convection may redevelop Monday, but the trend will shift
into eastern portions of the cwa, that have not experienced as
high of rainfall totals and should be able to handle any locally
heavy rainfall that occurs. 07 .

Long term... Monday night through Sunday night
southwest flow aloft will prevail through much of the extended
periods and this will result in a rather wet period, especially
across our southern and eastern most zones initially. The frontal
boundary associated with the weakening surface low pressure system
over texas will lift to the northeast as a warm front and texas
extends from parts of arkansas into northern mississippi and
alabama. Rain chances will decrease over the more western zones,
however the region between the upper level ridge of high pressure
off the southeast seaboard of the atlantic and over the northeast
gulf of mexico and the southeast side of the large and broad upper
level trough of low pressure over the central CONUS will allow
disturbances and available moisture to produce convection. Our next
cold front will arrive late Tuesday night and on Wednesday and moves
across much of the forecast area before becoming nearly stationary
along the southern periphery and remaining a focus for showers and
thunderstorms through Thursday. Upper flow will remain from the
southwest which will result in continued pops beyond midweek with
the front trying to return back north but a backdoor front shifts
into the region from building surface high pressure over the
tennessee and ohio valleys with the main cooler air moving into the
southeast states and east and northeast parts of the four state
region. The western end of the surface boundary becomes nearly
stationary late Friday night into early Saturday which may provide a
brief period of no rain chances. The ridge of high pressure off to
the east retrogrades over the forecast area and amplifies across
much of the gulf coast states and into the central sections of the
country. Rain chances will be hit or miss during most of the weekend
and diurnally driven through the weekend and start of the next work
week. 06

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.
