(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kcle 231613 afdcle area forecast discussion national weather service cleveland oh 1213 pm edt Thu may 23 2019 Synopsis Low pressure will cross the upper great lakes today with a cold front settling south across the area this evening. High pressure from the northern plains will build east across the region on Friday. A warm front will lift north on Saturday then sink south again on Sunday maintaining a focus for active weather. Near term through Friday Update... Adjusted pops and clouds based on quickly changing radar and satellite. Quick look at afternoon forecast sounding imply we may not be quite done with convection. Mfd forecast li at 4pm is -8c with capes over 2800 j kg so boosted afternoon pops back into the southern tier. No other significant changes. Original... Low pressure is located over the arrowhead of minnesota this morning with a cold front extending south across illinois. The forecast area is starting off in the warm sector ahead of an MCS tracking across indiana. This convection has been maintained overnight as an upper level wave rides out of the plains towards the southern great lakes with a 65 knot low level jet. This jet is providing tremendous moisture advection into the region, working to overcome the very dry air noted above 900mb on the 00z dtx sounding. The 08z SPC mesoanalysis shows a large pw gradient across the state of indiana with a 0.6 inch pw near toledo and 1.7 inches near chicago. It is unclear to what extent this drier air will have on causing this complex to weaken as it approaches the i-75 corridor towards 11z or if the MCV and steep mid-level lapse rates will be sufficient to maintain storm intensity and prompt convective warnings towards sunrise. The rap suggests a corridor of instability will advect north ahead of the line with 750 j kg of ml cape, helping to maintain intensity until at least 8-10 am before starting to weaken. There is high confidence that thunderstorms with considerable lightning will move across the area this morning but at some point convection may become elevated, lessening the threat of severe weather. Coordination will continue with the storm prediction center this morning and severe thunderstorm watches warnings will be issued if needed. Latest runs of the hrrr indicate convection will be almost east of the forecast area by 16z. Morning thunderstorm activity will stabilize the atmosphere and take some time to recover into this afternoon. However many areas will clear out this afternoon allowing temperatures to approach 80 degrees with good mixing and breezy southwest winds gusting to 30 mph. Dewpoints will remain high in the mid to upper 60s ahead of the cold front this afternoon and expect CAPE values of 1000 j kg or more to develop across the southern counties. Sufficient forcing along the cold front may support redevelopment of scattered showers and a few thunderstorms this afternoon in the 21-01z time frame. We will monitor any storms to develop but expect the primary severe weather threat today to be this morning. High pressure will build in behind the front for Friday bringing a drier airmass and cooler temperatures. Highs on Friday will range from the mid 60s at the lakeshore to upper 70s south with thickening mid-cloud from the west during the afternoon. Short term Friday night through Sunday night Upper ridge will build over the ohio valley great lakes Friday night as a surface warm front lifts north of the area. A southwesterly low level jet will nose northeastward into the southern great lakes late Friday night into Saturday. Most of the overnight will be dry across the area, however some increased chances for precip arrive on the periphery of the LLJ by early Saturday morning. Instability will increase across the region through the day Saturday as a mid level shortwave approaches the region from the west. Good mid level flow and unstable conditions will result convection increasing across the area ahead of the wave, with the potential for some diurnally driven strong to possibly severe storms. Low level lapse rates will be steep with decent mid level lapse rates, and enough deep layer effective bulk shear to organize convective, initially |
discrete and possible growing upscale into something linear, with large hail damaging winds possible. The threat will be contingent upon how unstable the area gets through the day and the timing of any mid level forcing. Given the synoptic pattern Saturday night, it isn't out of the question that we could have upstream convection develop and move eastward into the area by early Sunday morning. A more potent wave is expected to track eastward across the region Sunday afternoon, with another round of convection expected. Model differences with the exact track timing of the forcing precludes anything more than low likely high chance pops Sunday tapering to slight chance chance pops Sunday night. Highs on Saturday will be in the low to mid 80s for much of the area, but will be a touch cooler Sunday in the upper 70s to low 80s. Long term Monday through Wednesday A brief lull in the active weather regime is expected Monday with a more amplified longwave pattern setting up and a period of ridging over the region Monday into Monday night. A warm front will lift north through the area Monday night into Tuesday as low pressure tracks northeast through the western great lakes, with some slight chance low chance pops forecasted. Upper ridging will hold across the region Tuesday, although the ridge will be a bit more flattened over the great lakes. Pops increase Tuesday night into Wednesday as low pressure tracks through the great lakes bringing a frontal boundary towards the area. Still kept pops in the low to mid chance range during this period with the better forcing west of the area, although the region will be unstable in the warm sector. Highs will generally be in the upper 70s to low 80s through the period. Aviation 12z Thursday through Monday Thunderstorm complex moving east across the area will bring thunderstorms with strong winds to areas from mfd-cle eastward through 15z. Gusts to 40 knots will be common with gusts to 50 knots possible. Brief heavy rain with ifr visibilities will be possible. After the morning activity moves through, the airmass will try to destabilize from mfd-cak and points south after 21z. Scattered thunderstorms may re-develop this afternoon in this area and may need to be added to the terminals. By late morning we will start to see southwest winds become breezy with gusts to around 25-30 knots. Winds will drop off to 5-15 knots tonight as they shift around to the northwest behind a cold front. Outlook... Non-vfr possible in thunderstorms Saturday and Sunday. Marine Low pressure tracking across the great lakes today will bring a cold front to the western end of the lake this afternoon, crossing the lake by the overnight hours. Southwest winds today ahead of the front will increase to 15-20 kts before becoming more west to northwest and weakening behind the front tonight. There may be a need for a small craft advisory on the western half of the lake this afternoon into this evening, however winds will remain just below criteria, and shore parallel flow should keep waves in the 2-4 ft range. High pressure will build east across the lake tonight through Friday before the front lifts back north across the lake as a warm from late Friday night through Saturday morning. This will keep winds out of the west southwest across the lake through Sunday, until another cold front sweeps across the lake, with winds becoming west to northwest Sunday night into Monday.
