NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Indianapolis in 
630 am EDT Tuesday Jul 22 2014 


Update... 
the aviation section has been updated below. 


&& 


Synopsis... 
issued at 204 am EDT Tuesday Jul 22 2014 


A warm...Summer day is expected today as high pressure east of 
Indiana provides warm and humid southerly flow to central Indiana. 
This will result in a typical Summer day. Tonight a quick moving 
cold front will push central Indiana from the northwest. This will 
result in chances for light showers or an isolated thunderstorm 
tonight. 


The cold front will push south of central Indiana on 
Thursday...allowing high pressure to return to central Indiana 
from the upper Midwest. The high will bring a return to cooler 
than normal temperatures and dry conditions for the rest of the 
work week. 


Another frontal system will bring more chances for rain during 
the weekend. 


&& 


Near term /today/... 


Issued at 204 am EDT Tuesday Jul 22 2014 


Surface analysis early this morning shows high pressure in place 
over the Middle Atlantic States. Light...southerly return flow was 
in place across Indiana and the Ohio Valley. Infrared failed to show any 
clouds in the Hoosier state. Dew point temperatures remained in the moist 
middle 60s...and some patchy fog was developing across the area. 


Main forecast challenge today will be temperatures. GFS and NAM suggest a 
ridge axis aloft stretching from broad high pressure over the 
Desert Southwest will pivot across Indiana today. This should 
result provide good subsidence aloft...diminishing cloud cover. 
Time height sections and forecast soundings remain dry through the 
day...with the NAM...GFS and European model (ecmwf) all suggesting convective 
temperatures in the 90s. Thus it will be hard to produce much cumulus 
or clouds today to hamper temperature rises. Forecast soundings 
show 850mb temperatures around 18c-19c. Mavmos continues to run too warm. 
Models also suggest a thermal axis aloft...northwest of central 
Indiana ahead of the approaching cold front over northern 
Illinois. Given this will trend temperatures 1-2 degrees cooler than 
mavmos at most spots...particularly at ind which has been running 
cooler. Look for warmest temperatures across the northwest and southern 
parts of central Indiana. 


&& 


Short term /tonight through Thursday night/... 


Issued at 204 am EDT Tuesday Jul 22 2014 


Main challenge during this period will be the cold front passage 
expected tonight. 


NAM and GFS continue to keep a strong ridge in place across the 
western United States. This in turn results in a continued Lee 
side flow from the northwest spilling into the Great Lakes and 
Indiana. Tonight...the GFS and NAM suggest a short waves slides 
down the from the Midwest...with the best dynamics a forcing 
flowing across the Great Lakes and Michigan. An associated cold 
front is expected to accompany this feature and pass across 
Indiana...mainly overnight. Essentially the tail of this cold 
front is what is left as it passes across Indiana...providing very 
limited forcing. Forecast soundings and time height sections fail 
to show deep saturation overnight. GFS 310k isentropic surface 
shows an axis of high specific humidities pushing across the 
state...over 9 g/kg. However no upglide is present. Lower level q 
vector convergence is very good across central Indiana as the 
front passes tonight. However...low level jet remains weak...with speeds 
around 20-25 knts through the night. Thus confidence is low for a 
soaking rain...although a few light showers cannot be ruled out. 
Will use some low chance probability of precipitation overnight. Given at least the 
expected cloud cover will trend low temperatures warmer than mavmos. 


Good cold air advection and subsidence then take place across the 
area on Wednesday as forecast sounding show a dry column. Surface 
high pressure builds into central Indiana...diving southeast out 
of south central Canada...bringing a cooler and dry Continental 
air mass to our region. This will result in dry and cooler weather 
through Thursday night at least. Forecast soundings on Thursday 
suggest attainable convective temperatures with a middle level 
inversion...once again suggest some harmless...low-topped flat cumulus 
during the afternoon hours. Given the good cold air advection in 
place on Wednesday and Wednesday night will trend highs and lows 
cooler than mavmos. Northerly surface slow continues through 
Thursday night. Given this pattern will work a blend of the mavmos 
and metmos. 


&& 


Long term /Friday through Monday/... 


Issued at 258 am EDT Tuesday Jul 22 2014 


Models are close enough that the allblend initialization was 
accepted for most parameters. 


Friday looks to remain dry. A front will move into the area and 
stall out this weekend. Areas of low pressure will move along the 
front. This will keep the threat for showers and thunderstorms in 
the forecast for Friday night through Sunday night. 


Confidence in which period will have the best threat for rain is low 
since timing of the waves of low pressure is uncertain that far out. 
Will keep allblend/S chance probability of precipitation. 


For Monday an upper trough will dig into the area and bring another 
cold front. This will also bring chances for rain to the area. 


Temperatures will average near to below normal through the 
period...with the coolest readings coming Monday as the upper trough 
moves in. 


&& 


Aviation /discussion for 221200z taf issuance/... 


Issued at 630 am EDT Tuesday Jul 22 2014 


VFR expected through most of the period. 


Based on similar conditions yesterday...expect bulk of fog to be 
gone by 12z. Kept some MVFR for an hour at klaf/kbmg. 


Otherwise expect some scattered cumulus today. As a cold front 
approaches tonight...expect an increase in middle and high clouds. Any 
convection associated with the front will be weakening as it moves 
into the area. Thus have only included vcsh at klaf for a few hours 
after 04z and left mention out for now elsewhere. 


Winds will shift to the northwest late in the period with the front. 


&& 


Ind watches/warnings/advisories... 
none.
