The Storm Prediction Center (SPC) Weather Outlooks Web Service <\/b> offers various polygon layers representing Convection Outlooks from Day 1 to Day 3. These encompass Category Outlooks for Significant and Probabilistic Tornado, Hail, and Wind Outlooks. Additionally, the service provides layers displaying forecasted polygons for Day 4 to Day 8 Probabilistic Outlooks. Further details regarding the layers included in this map service are outlined below.<\/span><\/p>

Day 1 <\/span>Layer contain: Separate 5-tier categorical, probabilistic tornado, hail and wind, significant tornado, hail and wind outlooks.<\/span><\/p>

Day 2 <\/span>Layer contain: Separate 5-tier categorical, probabilistic tornado, hail and wind, significant tornado, hail and wind outlooks.<\/span><\/p>

Day 3 <\/span>Layer contain: 5-tier categorical outlook, probabilistic severe, and significant severe.<\/span><\/p>

Days 4-8 <\/span>Layers are all probabilistic outlooks.<\/span><\/p>

Update Frequency: <\/span><\/p>

Day 1 updates daily at 01Z, 06Z, 13Z, 16:30Z, and 20Z<\/p>\n

Day 2 updates daily at 06Z and 17Z<\/p>\n

Day 3 updates daily at 07:30Z<\/p>\n

Day 4-8 updates daily at 09Z<\/p>
