Short Term
Tonight...and Saturday

Quiet weather was observed across the region early this morning. A band of mid-level clouds was gradually expanding south across the region, in association with a short-wave trough and the LFQ of an upper level jet streak. Just north of this cloud band, some patchy fog had developed in Vilas County.

Cooler but seasonal temperatures and lower humidity can be expected through Saturday, as Canadian high pressure dominates our weather. Highs both days should be in the 70s, with lows tonight ranging from the upper 40s to middle 50s.

For today, morning clouds should erode as the short-wave exits this morning. A few models show scattered afternoon showers developing near a weak inverted surface trough and convergence zone in central WI. Have opted to keep any mention of these showers out of the forecast, given the proximity of the Canadian high and a drier air mass. Dry weather prevails through Saturday morning, but developing WAA on the western periphery of the departing high and the arrival of a short-wave trough may trigger scattered showers in parts of C/NC WI later Saturday afternoon.

Long Term...Saturday Night Through Thursday

The 500mb pattern for next week will feature a ridge across the eastern United States with a trough across the western United States. This pattern will result in the area being in the ring of fire with thunderstorm complexes moves across the area from time to time through the middle of next week.

For Saturday night, an increasing low level jet approaching 50 knots will be the focusing mechanism for the development of showers and scattered thunderstorms during the evening across central and north-central Wisconsin. The main difference tonight is the rain may be a little bit slower to arrive/develop across east-central Wisconsin. I lowered rain chances in this area during the evening hours. The showers and storms will expand/move across the area overnight. There will be likely be more activity around during the morning across northeast Wisconsin. This activity could result in a slower push of the warm front northward Sunday afternoon which could impact high temperatures and the possibility of redevelopment of storms along the warm front Sunday afternoon into Sunday night.
Bufkit soundings impressive with 3,000 to 4,000 J/KG of cape with shear values around 30 knots. The big issues in the soundings is the warm layer between five and seven thousand feet that would inhibit thunderstorm development. More likely will need to watch boundary across northeast Minnesota and northwest Wisconsin, or along the lake breeze boundary near Lake Superior for focused development of storms. The Storm Prediction Center Day 3 Outlook has a marginal risk of severe storms, mainly for Sunday afternoon into Sunday night.

For Monday and Tuesday, the GFS solution is further south with the frontal boundary compared to the ECMWF/Canadian model, which would support highs in the middle 80s to lower 90s with afternoon heat index values from the upper 80s to middle 90s. Will need to watch for thunderstorm complexes along the front that could make a move into the forecast area both days. With the abundant heat and humidity, there is the potential for stronger storms and locally heavy rainfall. It appears Wednesday will be somewhat cooler as the frontal boundary is expected to move across the area which will result in additional chances for stronger storms and heavy rain. Temperatures will likely be closer to normal Thursday.

for 12Z TAF Issuance Issued at 628 AM CDT Fri Jun 14 2024

A short-wave trough was generating widespread mid-level clouds and a narrow band of light showers or sprinkles early this morning.
These should exit by mid to late morning as the short-wave shifts east. SCT-BKN high-based cumulus will then develop away from the lake in the late morning and afternoon, and there could be a few light showers or sprinkles near a convergence zone in central WI.
Clearing skies are expected by evening.

Light E-NE winds will become southeast later this afternoon into tonight.
