704 pm edt Tue may 21 2019

High pressure continues into tonight. Much warmer Wednesday
into the weekend with chances for showers and thunderstorms
somewhere in the area each day.

Near term through Wednesday
As of 130 pm Tuesday...

an upper level ridge axis will work its way into the forecast
area from west to east through the night. These rising heights
will keep precipitation at bay... However we do have a fair
amount of clouds across the forecast are as cirrus aloft and
some diurnal cumulus below that. These clouds have really
tempered temperatures so far today, but visible satellite shows
increasing sunshine is working in from the west, so did not
significantly cut back temperatures for the remainder of the

Surface high pressure slides to the east overnight, which will
turn winds around to southerly by morning. Have slightly non-
diurnal trend for hill tops across the south through the pre-
dawn. This will also bring a significantly warmer day on
Wednesday. The upper ridge axis starts heading east by late
afternoon which may allow a shower or storm to drift into the
far northern CWA by late afternoon evening.

Short term Wednesday night through Thursday night
As of 235 pm Tuesday...

for Wednesday, broad high pressure will sit just south of the area
which will help yield and weaken a frontal boundary trying to
slide into the area from the west. Still a chance for some light
showers, however it looks like most of the energy will be
suppressed from the ridging and drying of mid levels. With
the elevated instability that models hint at, there is still a
threat for thunderstorm activity which will mostly be diurnally
driven. Since instability will be relatively weak, not
expecting anything severe at this time.

Once the boundary moves past the area another more organized
frontal boundary moves closer on Thursday and a wave of energy
traverses around the clockwise flow of the ridge and impacts our
area. The precipitation shield ahead of the cold front
associated with a surface low over the great lakes will
overspread the area along with the aforementioned disturbance.

Rain showers and thunderstorms will be an issue in the afternoon
with a frontal boundary associated with the low providing
plenty of lift and moisture. Along with high instability (ml
cape 3000+ j kg) and shear over 40kt, storms are capable of
producing severe hail and damaging wind. SPC has our northern
half of the area in a marginal to slight risk for severe. Most
of the energy will ride along this clockwise path and exit

Long term Friday through Tuesday
As of 235 pm Tuesday...

Friday should be a relatively quiet weather day with high
pressure ridging and lack of any real ascent, however a diurnally
driven shower or storm cannot be ruled out with modest instability
expected. On Saturday, another system with a frontal boundary will
affect the area and provide ample moisture and instability for more
potential thunderstorms. High pressure shifts slightly south
allowing multiple waves to rotate around to the area through
Sunday for more unsettled weather.

Models indicate a frontal boundary and associated surface low
pressure system to the west will hang around until the beginning
of the new week (mon-tues). On the other hand, models battle
each other with trying to build in high pressure sooner, while
the upper low loses focus and strength. Thus, confidence of
timing and strength of this system is low. There is a hint of
another system around the middle of next week. At any rate, with
models being in such disagreement there is very low confidence
on timing of these systems. Continuing heat with temperatures in
the upper 80's along with plenty of moisture and chances for
thunderstorms will be the moral of this long term forecast.

Aviation 00z Tuesday through Sunday
As of 700 pm Tuesday...

vfr conditions can be expected through the period, with the
possible exception of some showers or thunderstorms late
Wednesday afternoon in southeast ohio.

Forecast confidence and alternate scenarios through 00z

forecast confidence: high.

Alternate scenarios: none.

Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.

M = medium: TAF has varying level of consistency with models.

L = low: TAF inconsistent with all models or all but one model.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
