The same idea applies to the precipitation normal values, except enhanced odds forĪbove- (below-) normal precipitation values are green (brown). If the selected point is within an area of enhanced odds forīelow-normal temperatures, the shading around the normal maximum/minimum temperature will appear blue. If the selected point is withinĪn area of enhanced odds for above-normal temperatures, the shading around the normal maximum/minimum temperature will appear red. Yesterdays Radar Loop shows areas of precipitation for the prior day. The color used to highlight the normal values (precipitation or maximum/minimum temperature) are used to delineate the category of the forecast at the point clicked. What does the highlighting around the normal precipitation or normal maximum/minimum temperature imply? What color scheme is used? The color scheme follows that of the static images for the 6-10 day forecasts and 8-14 day forecasts. Intervening values are linearly interpolated, combined with data from the COOP, and averaged over the 7-day period to createĪverage maximum/minimum temperature normals. Active Storms (0) Past Storms (1972-2024) Sea Surface Temperature. For temperatures, monthly average maximum/minimum temperatures are assigned to theġ5th of the current month and subsequent month. These values are then summed over the 7-day period to create total precipitation normals. PRISM data are inherently available as monthly values.įor precipitation, daily average values are calculated (Monthly Total/Number of Days in Month) and combined with data from the Cooperative Observer Network (COOP). PRISM (Parameter-elevation Regressions on Independent Slopes Model) normals are used in this display.
