SYNOPSIS. Showers and thunderstorms will be crossing the area today with the passage of a cold front. High pressure returns dry and seasonably cool conditions for the first half of the weekend.
NEAR TERM /THROUGH TONIGHT/. Mesoanalysis shows a notable vort max/shortwave exiting MI that is driving convection over OH to northwest PA. This feature is expected to glide north of Pittsburgh this morning and help maintain/foster convective activity. Storms will generally remain sub-severe with the lack of notable instability in place while temporarily maintaining enough cloud cover to slow sfc warming.
After the shortwave passes, there will likely be a brief lull in activity before the approach/passage of the sfc cold front this aftn/eve potentially generates another round of convection. If enough clearing can occur to boost area temperature and destabilize the region, a more significant severe threat favoring damaging wind and large hail could develop given ample shear and intruding dry air in the mid levels. Confidence remains low on this threat as it remains unclear how quickly, or if at all, clouds will clear to allow for sfc warming. It will be largely dependent on the evolution of the morning convection that has been poorly modeled up until this point.
Overnight, additional weak shortwaves in the upper trough may develop iso/sct showers with localized thunder. Otherwise, drier conditions are expected as high pressure and cold advection develop behind the exiting cold front
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. High pressure will slowly build in from the northwest on Friday with dry conditions expected through Saturday. Temperatures will run below seasonal averages under cold advection.
LONG TERM /SUNDAY THROUGH WEDNESDAY/. Another shortwave within the broad eastern U.S. upper trough will push a weak sfc cold front through the region Sunday, increasing precipitation chances.
High pressure should resume influence over the upper Ohio River Valley heading into next week under weak upper troughing, with temperature near to slightly below seasonal averages.
AVIATION /13Z THURSDAY THROUGH MONDAY/. An upper trough/MCV is expected to track across the Lwr Great Lakes/Upper OH Valley region by mid to late morning, spreading showers and a few embedded tstms across area ports. Included an MVFR tempo mention in the tafs for this scenario, though confidence remains low-medium in this solution, with model initialization being less than optimal.
After the initial wave exits, additional sct tstms are possible along an associated sfc cdfnt. Maintained a VCTS mention in the TAFs for this potential, though again confidence is low on timing/extent of covg due to cloud cover and precip from the upper wave. MVFR cigs are expected late tonight after FROPA.
Outlook. Restrictions are psbl with a Sun cdfnt.
