Area forecast discussion, May 8, 2:34 PM EDT, 1 minute before
AREA FORECAST DISCUSSION National Weather Service Northern Indiana 234 PM EDT Mon May 8 2017 .SYNOPSIS... Issued at 230 PM EDT Mon May 8 2017 Dry conditions will persist through this evening, then showers and a few thunderstorms are expected toward sunrise and continuing through Tuesday morning Tuesday...mainly along and south of highway 30. Lows tonight will range from the mid 40s southwest to the mid 30s northeast where some patchy frost is possible. Highs tomorrow will struggle into the 50s due to rain for some and clouds. && .SHORT TERM...(This Evening through Tuesday) Issued at 230 PM EDT Mon May 8 2017 General decay/flattening of prior anomalous deep layered trough from James Bay sewd through New England has allowed sharp low level baroclinic zone to intrude back newd into the srn lakes as denoted in aggregate extensive accas cloud field from sw WI sewd through cntrl IL. 00 to 12Z model trends have continued to buck even further newd with tight H85 thermal boundary overnight as fairly strong LLJ of 40kts overruns the frontal zone. Upstream low level thermal ridge is fairly unstable and with relatively low WBZ heights in place along wrn extent of retreating CP airmass...some threat for isold severe hail given fairly steep mid level lapse rates and sufficient deep layer shear. Primary change was to notch pops higher esp sw third and spread a bit higher chc pops northeast. && .LONG TERM...(Tuesday Night through Monday) Issued at 230 PM EDT Mon May 8 2017 Primary model based contention this period continues to be nrn bound of near stationary warm frontal zone bisecting warm mid level ridge across the plains and cold upper trough split between Hudson Bay and the Gulf of Maine. Wavy disturbed flow aloft hard to model at this range but would appear srn extent/influence of upstream sw amplifying through the base of wrn Hudson Bay low center brings another good shot of overrunning Wed night. This was already accounted for in prior grids yet given consensus 12Z signals a prudent sig pop bump looks warranted. In wake of this disturbance...low level baroclinic zone expected to shift south of the OH river with dry weather and moderating temps going into the Mothers Day weekend. However remnant Hudson Bay low will need to be watched as it will have a propensity to dislodge swd across the lakes and bring another chc of rain through the srn lakes Sat morning. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon) Issued at 133 PM EDT Mon May 8 2017 VFR conditions will persist through most of the overnight period with very dry and subsident airmass in place. Sharpening baroclinic zone currently to the southwest will lift into the area late tonight. Increasing fgen will support a narrow band of lower clouds and rain. Still some uncertainty as to whether the better low level convergence/moisture will impact the terminals. Left late period VFR but fuel alternate MVFR possible if main fgen band lifts far enough NE. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
