Short term...(today through Friday afternoon)
issued at 330 am EDT Wednesday Jun 19 2013
Short term forecast concerns remain minimal with high pressure
continuing in control of the weather today through Thursday resulting in
fair weather. Maximum temperatures will reach the 70 to 75 degree range today. It
will become warmer Thursday as winds become southwesterly and help
to boost maximum temperatures into the middle 70s to lower 80s.
We will keep a dry forecast going through Friday with 00z NAM/GFS
guidance showing any showers or storms Friday afternoon should stay
north to northwest of our forecast area. The moderating trend of temperatures will
continue on Friday due to continued south to SW flow warm air advection and maximum
temperatures will reach the lower to middle 80s.
Long term...(friday night through tuesday)
issued at 330 am EDT Wednesday Jun 19 2013
Forecast issue in the extended is how extensive showers and
thunderstorms are as a warm front slowly moves through over the
weekend. This could be complicated by mesoscale convective system activity and resulting
outflow boundaries. Looks like Saturday could have the best chance
for rain as convection fires up along the warm front. Will carry
slight or chance probability of precipitation over the weekend and into Tuesday shaded lower
further south where capping effect of upper ridging will be more
likely to limit convection potential.
