The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Northern Indiana wrote its last area forecast discussion before this special weather statement went out at Jul 20, 3:07 PM EDT, 1 hour 28 minutes earlier.
Area forecast discussion, Jul 20, 3:07 PM EDT, 1 hour 28 minutes before
Area Forecast Discussion National Weather Service Northern Indiana 307 PM EDT Fri Jul 20 2018 .SYNOPSIS... Issued at 106 PM EDT Fri Jul 20 2018 Numerous showers and thunderstorms are expected this afternoon as a strong upper level disturbance tracks through. A few thunderstorms may become severe with damaging winds, small hail, heavy rain, and perhaps an isolated tornado the threats. Chances for on and off showers will remain in the forecast tonight through Sunday. Lows will be in the 60s and highs will be in the 70s this weekend. A mainly dry and warmer pattern is expected next week. && .UPDATE... Issued at 303 PM EDT Fri Jul 20 2018 Main focus through 21/22z will remain maintenance/intensity of quasi-linear line segment nearing the I-69 corridor as of 19z. Several brief bowing segments and mesovorts noted but nothing reported with line so far. Effective shear values of 25-30 knots enough for this organization though activity now pushing east into a more stable environment as warm sector erodes with front now occluded. Will carry the Tornado Watch through the late aftn into ne IN/sc Lower MI with possible extension east into nw OH if QLCS strengthens. Isolated tornadoes and damaging winds will be the primary threat, best chances over the next 2 hours. && .SHORT TERM...(Tonight through Sunday) Issued at 303 PM EDT Fri Jul 20 2018 Vigorous vertically stacked low in southeast WI will wobble slowly southeast into southern Lake MI tonight and over the local area on Saturday. Deep moisture associated with this feature and series of vort maxes to rotate around the upper low will keep showers and chances for isolated storms in the forecast during this time. Greater coverage and intensity is expected late this aftn/early eve and again Saturday afternoon thanks to daytime heating. Strong- severe storms are not expected tonight-Saturday, though will have to keep an eye out for funnel clouds/landspouts Saturday afternoon given the ambient vorticity near the low. Overcast/moist airmass limits diurnal temp ranges otherwise with lows in the 60s tonight and highs mid 70s tomorrow. Shower coverage/chances the gradually diminish into Saturday night and Sunday as main circulation and stronger deformation forcing shifts off to the south. Drier air and some subsidence may also work in by Sunday, especially across northern portions of the forecast area. Temps will likely be a few degrees warmer on Sunday with highs generally in the upper 70s. && .LONG TERM...(Monday through Friday) Issued at 303 PM EDT Fri Jul 20 2018 A rather typical late July week is expected with seasonable temps and mainly dry conditions. Did retain very low PoPs for afternoon showers on Monday and Tuesday southeast of US 24 given close proximity to a leftover trough axis. Otherwise temps warm a bit into Tuesday-Wednesday before broad troughing redevelops over the Great Lakes supporting slightly cooler temps and low humidity by Thursday and Friday. && .AVIATION...(For the 18Z TAFS through 18Z Saturday Afternoon) Issued at 106 PM EDT Fri Jul 20 2018 Thunderstorms with sig restrictions and potentially some stronger wind gusts will be the primary concern this afternoon as a strong vort max and occluded front traverse northern IN. Latest radar and hi-res guidance hints at main impacts between 1730 and 1930z at KSBN and between 1930-22z at KFWA. These thunderstorms may become severe. VFR to low MVFR cigs with breezy ssw winds otherwise this afternoon. An upper low will bring lowering cigs and on and off showers to the area tonight into Saturday, best chances for rain and eventually IFR stratus at KSBN in closer proximity to the main circulation center. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE. LM...Small Craft Advisory until 6 PM EDT this evening for LMZ043-046. && UPDATE...Steinwedel SYNOPSIS...Steinwedel SHORT TERM...Steinwedel LONG TERM...Taylor AVIATION...Steinwedel Visit us at www.weather.gov/iwx Follow us on Facebook...Twitter...and YouTube at: www.facebook.com/NWSNorthernIndiana www.twitter.com/nwsiwx www.youtube.com/NWSNorthernIndiana
