DAVISWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Milwaukee, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at May 28, 3:06 PM CDT, 4 hours 3 minutes earlier.
Area forecast discussion, May 28, 3:06 PM CDT, 4 hours 3 minutes before
Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 306 PM CDT SAT MAY 28 2016 .TONIGHT AND SUNDAY...Forecast Confidence...Medium Scattered thunderstorms southwest of the forecast area are beginning to form into a line. A shortwave will bring this line of storms into the forecast area from late afternoon into the evening. More daytime heating will be available in the the western forecast area as the storms move through, so better bet for a few severe storms there. A severe thunderstorm watch is thus in effect for western portions of the forecast area. SPC is highlighting damaging winds is the primary severe threat, though some large hail and a tornado are not out of the question. Storms should exit the east by mid/late evening, with dry weather then expected overnight. The main trough axis is expected to move through on Sunday, bringing a chance for a few showers and storms. Should see decreasing precip chances and clouds from southwest to northeast later in the day, so have mildest temps in the southwest. Temps will be above normal again. .SUNDAY NIGHT AND MONDAY...Forecast confidence is high. It looks like we'll have a warm and dry Memorial Day. High pressure will take control with the column showing a significant lack of moisture. So, should see abundant sunshine with highs in the lower to mid 80s. If we do see any showers, it would be later in the afternoon and most likely along the WI/IL border southwest of Madison, but that threat looks low enough that we can leave it out. .TUESDAY THROUGH THURSDAY...Forecast confidence is medium. Ridging will slide east, allowing a very slow moving trough to approach then move through the Upper Midwest during this period. Look for showers and storms from time to time with the best chance for rain Tuesday night and Wednesday. The surface trough/front will likely exit far eastern Wisconsin by early Thursday morning. Some lingering showers on Thursday and turning a bit cooler with lower dewpoints. .FRIDAY AND SATURDAY...Forecast confidence is medium. Cooler high pressure settles across the area. This looks like a dry period. && .AVIATION/00Z TAFS/... Mainly VFR conditions are expected into tonight (other than lower conditions possible in storms). A line of showers and storms will likely arrive in the western forecast area by late afternoon, progressing eastward across southern Wisconsin during the evening hours. Could see a strong/severe storm or two, particularly from Madison westward. A chance for showers and storms will linger on Sunday as the upper trough moves through. Models are suggesting a return of some lower ceilings for a while as the trough slides through. && .MARINE... Southerly winds will keep some patchy fog over the nearshore waters at times through tonight. The fog could be briefly dense. Southwest to west winds Sunday should bring an end to the fog. A few gusts to 25 knots are not out of the question through late this afternoon and again Sunday afternoon. Overall though, conditions seem too borderline for a Small Craft Advisory. && .MKX Watches/Warnings/Advisories... WI...None. LM...None. && TONIGHT/Sunday AND AVIATION/MARINE...DDV Sunday NIGHT THROUGH Saturday...Davis
