ISSUED AT Friday, May 15, 2026 at 11:04 AM CDT ISSUED BY National Weather Service Green Bay WI HEADER URGENT - FIRE WEATHER MESSAGE # PRECAUTIONARY/PREPAREDNESS ACTIONS -------------------- A Red Flag Warning is issued when critical fire weather conditions are imminent. A combination of strong winds, very low relative humidity, warm temperatures and exceptionally dry fuels will create dangerous wildland fire conditions. Persons are urged to be careful with any activities that could potentially lead to a wildland fire. Campfires, outdoor grills, smoking materials, chain saws, and all-terrain vehicles all have the potential to throw a spark and ignite a dangerous and destructive fire. Please advise the appropriate officials or fire crews in the field of this red flag warning. # AREAS AFFECTED -------------------- Vilas

# HEADLINE -------------------- NEAR CRITICAL TO CRITICAL FIRE WEATHER CONDITIONS EXPECTED ACROSS PARTS OF NORTHERN WISCONSIN THIS AFTERNOON AND SATURDAY # SUMMARY -------------------- Pine fuels have reached their peak volatility and fine fuels have still not greened up over northern Wisconsin, so periods of dry and windy weather will bring near-critical to critical fire weather conditions through Saturday. Critical fire weather conditions are expected across far north central Wisconsin this afternoon and early evening, and a Red Flag Warning has been posted for Vilas County. Despite light rainfall overnight, fine fuels should have an opportunity to dry out by afternoon. Weather conditions should reach critical levels, with highs around 80, low relative humidity and southwest winds gusting to 25 to 30 mph. Very dry air will reside over northern Wisconsin on Saturday. Very low relative humidity, west winds gusting to 25 mph and warm temperatures will lead to near-critical to critical fire weather conditions across the Northwoods Saturday afternoon. Residents are urged to be careful with any activities that could potentially lead to a wildland fire. Campfires, outdoor grills, smoking materials, chain saws, and all-terrain vehicles all have the potential to throw a spark and ignite a dangerous and destructive fire. # DETAILS -------------------- ISSUED AT Friday, May 15, 2026 at 3:39 AM CDT ISSUED BY National Weather Service Green Bay WI HEADER Special Weather Statement # AREAS AFFECTED -------------------- Calumet, Langlade, Southern Oconto County, Wood, Brown, Door, Florence, Forest, Kewaunee, Lincoln, Manitowoc, Marathon, Menominee, Northern Marinette County, Northern Oconto County, Oneida, Outagamie, Portage, Shawano, Southern Marinette County, Vilas, Waupaca, Waushara, Winnebago

There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS IOWA THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE UPPER MIDWEST AND CENTRAL/SOUTHERN PLAINS SUMMARY Severe thunderstorms capable of producing severe/damaging winds and large to very large hail are likely late this afternoon and evening centered across much of Iowa. Isolated to scattered severe hail and damaging winds are possible over a broader area from parts of the southern High Plains to the Upper Midwest. Central Plains into the Upper Midwest including Iowa A cyclonically influenced moderately strong belt of westerlies will exist over the northern Plains to Upper Midwest and upper Great Lakes. The primary surface low will remain in northern Ontario, with a trailing cold front extending southward into the Upper Midwest and northern/central Plains. A secondary surface low will exist across southwest Kansas and northwest Oklahoma around peak afternoon heating, with a dryline extending south-southwestward from this low across much of the southern High Plains. Continued expectations are for robust thunderstorm development along the cold front/surface trough from eastern Nebraska into Iowa to be delayed until late afternoon or early evening (around 22-00Z), as large-scale ascent will remain weak until a low-amplitude shortwave trough embedded within the westerly mid-level flow eventually overspreads the surface warm sector. Continued low-level warm/moist advection through the day and diurnal heating will contribute to the development of moderate to locally strong instability (2500+ J/kg MLCAPE) across this region by early evening. While low-level winds are forecast to remain fairly modest, enhanced mid/upper-level flow will support sufficient (35-50 kt) deep-layer shear for updraft organization. Initial supercells should pose a threat for large to isolated very large hail (2+ inches in diameter), before likely quick upscale growth this evening across Iowa with an increasing potential for scattered severe/damaging winds. Some of these gusts could exceed 75 mph on a localized basis given the expectation for an organized cluster and ample instability. A tornado or two could also occur this evening as low-level shear gradually increases with a strengthening low-level jet. Southern High Plains While clouds linger at midday, particularly with southward extent across west/southwest Texas, robust daytime heating will yield a very well-mixed/deep boundary layer near/south of the secondary surface low over southwest Kansas/northwest Oklahoma. Mid-level temperatures will remain cool enough to support at least weak instability, even with modest low-level moisture/surface dewpoints. A weak mid-level shortwave trough moving from the southern Rockies into the southern High Plains will enhance large-scale ascent late in the day. This should support the development of high-based thunderstorms, with occasional strong to severe wind gusts expected. Latest short-term guidance suggests a more probable zone of thunderstorm-related gust potential may focus across the Texas South Plains and Low Rolling Plains. Isolated gusts of 70+ mph may occur given the very deeply mixed boundary layer extending up to around 500 mb. Cells that develop in west/southwest Texas may also contain some hail, with elongated hodographs in mid/upper levels.

Pollen Index: 8.6 Pollen Level: medium-high Predominant Pollen: Ash, Oak and Birch. The amount of pollen in the air for Saturday will be higher than they were today in the high range. This rise is a result of higher temperatures and the lower dewpoint. If you do suffer from allergies tomorrow could be more difficult.
