LATEST DETERMINISTIC/HI-RES MODELS SUGGEST ISOLATED STORMS DEVELOPING AROUND 00Z...WITH MORE WIDESPREAD COVERAGE POSSIBLE THEREAFTER. THE PRESENCE OF AN EML HAS WIDELY LIMITED CONVECTIVE DEVELOPMENT ACROSS THE SRN PLAINS THROUGH THE AFTERNOON. HOWEVER...THE APPROACH OF AN UPPER TROUGH AND ASSOCIATED COOLING ALOFT IN COMBINATION WITH ADEQUATE HEATING/MOISTENING OF LOW LEVELS HAS GRADUALLY BEEN ERODING CONVECTIVE INHIBITION...EVIDENCED BY AN EXPANSIVE CU FIELD THAT IS BEGINNING TO DEVELOP ALONG AN APPARENT WEAK COLD FRONT/DRYLINE. LOW LEVEL FORCING ALONG THIS FEATURE SHOULD BE SUFFICIENT FOR AT LEAST ISOLATED STORMS TO DEVELOP OVER THE NEXT FEW HOURS. STEEPER MID-LEVEL LAPSE RATES NEAR 8 C/KM AND SUFFICIENT CLOUD BEARING SHEAR SHOULD SUPPORT OCCASIONAL ROTATION AND LARGE HAIL FORMATION IN STORMS THAT CAN SUSTAIN A STRONGER UPDRAFT...WITH A RISK FOR DMGG WINDS AND PERHAPS AN ISOLATED TORNADO SHOULD MORE SURFACE-BASED CONVECTION BECOME APPARENT. RELATIVELY WEAK LOW LEVEL FLOW IN COMPARISON TO AREAS FARTHER N AND LARGE T/TD SPREADS MAY LIMIT A MORE WIDESPREAD TORNADO THREAT.

upsloper Posted April 10, 2011 Share Posted April 10, 2011 Cell N of Galesburg, IL has been maintaining itself pretty nicely. It's small now due to relatively low CAPE but will have an opportunity to grow and intensity as it heads NE into better instability and low-level shear. This cell or others from this cluster could affect the Chicago area if they intensity much further, taking a more right-hand turn. Link to comment Share on other sites More sharing options...
JoMo Posted April 10, 2011 Share Posted April 10, 2011 That forward speed is what really causes problems. It comes up on you fast.
