* Visibilities... areas of dense fog will result in the visibility
dropping to a quarter of a mile or less.

* Timing... the fog will persist early this morning... with
visibilities improving between 9 and 10 am.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Wilmington Ohio 
700 am EDT Sat Aug 23 2014 


Synopsis... 
warm and humid conditions will continue through the weekend into 
next week. After a foggy start today...upper level disturbances 
will interact with a surface front...providing a chance for 
showers and thunderstorms. An upper level ridge will build into 
the region Sunday into early next week...providing increasing heat 
and a decreased chance of thunderstorm activity. 


&& 


Near term /until 6 PM this evening/... 
updated... 
in the very moist boundary layer...light winds and 
partial clearing has led to the development of widespread fog. 
Visibilities at many locations have dropped and the fog has become dense. 
Therefore have issued a dense fog advisory for the entire area 
through 10 am. 


Previous... 
middle/upper level ridge over the nations middle section to amplify today. 
With this ridge sharpening up...surface boundary will meander through the 
western portion of iln/S forecast area. A gradient of instability is expected with 
moderate instability expected in the west and south closer to the frontal 
boundary. Will continue to mention high chance probability of precipitation across this favored 
area and trend probability of precipitation down to slight chance in the NE. 


High today to range from the middle 80s northeast to near 90 extreme 
SW. The hot temperatures in the SW combined with surface dew points in 
the lower 70s will result in heat indices in the middle/upper 90s. Will 
continue to mention this heat over the far SW in the severe weather potential statement product. 


&& 


Short term /6 PM this evening through Monday/... 
scattered storms expected to be ongoing this evening with the 
best coverage over the southwest. These storms will drop southeast 
around the periphery of the upper level ridge. Expect this precipitation 
to push south of ilns forecast area and weaken tonight tonight. In muggy 
airmass low temperatures to range from the middle/upper 60s NE to the 
lower 70s SW. 


Upper level flow continues to amplify Sunday with the ridge building 
northeast into the Great Lakes region. Under the influence of this 
ridge do not expect organized convection. Will limit probability of precipitation to over a 
slight chance of a thunderstorm...mainly during afternoon/early 
evening hours. 


Highs to warm up a little and range from the upper 80s to near 90 SW. 
Heat indices will top out in the middle and upper 90s in the far SW..so 
will continue to mention heat for Sunday afternoon in severe weather potential statement. 


Any storm that develop will be diurnally driven and expect to 
diminish Sunday evening. Muggy and warm conditions to persist with 
Sunday nights lows in the upper 60s and lower 70s. 




Instability gradient will exist Monday with low end moderate instability 
developing into the south and west during the afternoon. Will limit probability of precipitation to 
chance category in the far south but this may need to be expanded 
across the west. Very warm highs again in the upper 80s to around 90. 
Will continue severe weather potential statement mention of heat indices in the upper 90s across far 
SW. 


&& 


Long term /Monday night through Friday/... 
an upper level ridge axis will be situated southwest to northeast 
across the area early next week. This will help keep temperatures 
above normal through at least Tuesday so will nudge temperatures up a bit 
warmer than what is suggested by guidance with highs generally in 
the upper 80s to near 90 degrees. This will allow for some decent 
instabilities to develop Tuesday afternoons. However with the 
high overhead and limited forcing...think any thunderstorm 
activity will be fairly isolated Tuesday afternoon. 


The upper level ridge will begin to weaken through middle to late week 
as short wave energy lifts northeast into the Great Lakes region. 
This will eventually help push a cold front down into the Ohio 
Valley late in the work week but there are model differences as to 
exactly how fast this will happen. The 12z GFS remains the most 
aggressive with the front...pushing it through faster and farther 
south than both the 12z European model (ecmwf) and 12z CMC. Have generally taken a 
blend of the models...allowing for increasing probability of precipitation from the 
northwest later Wednesday and on into Thursday...then lingering some 
lower end probability of precipitation into Friday across the southeast to account for the 
slower ECMWF/CMC. Temperatures will of course be dependent on the 
frontal timing with cooler temperatures eventually moving in behind 
the front late in the period. 


&& 


Aviation /12z Saturday through Wednesday/... 
weather map features an upper ridge centered to the west and a weak 
surface high over the Ohio Valley. Visibilities are reduced as 
low as vlifr due to fog and br that have formed in a humid airmass 
under mainly clear skies and light winds. A period of MVFR 
ceilings may follow the dissipating fog and br. VFR should return 
to all sites by 17z. Day cvg and luk may see a few showers late 
in the forecast period when a disturbance in the mean upper flow 
rounds the eastern flank of the upper ridge. Fog is expected again 
late in the forecast in the persistent weather regime. 


Outlook...MVFR to IFR visibilities possible Sunday morning.
