Unsettled Weather In the West; Above Average Temperatures in the Central U.S.

A relatively quiet stretch of weather is expected across much of the Continental U.S. with the exception of the West Coast where rain and higher elevation snow will impact the Northwest and northern California through Tuesday. An elevated fire weather risk is expected in portions of the southern and central Plains. Record high temperatures are possible across the Northern Plains and Upper Midwest. Read More >

The resulting graphic displays forecast vertical wind profiles over the selected location from the surface up to 2,000, 5,000, 10,000, or 20,000 feet AGL.
The graphic is updated based on the latest run of the HRRR, RAP, HiResW, NAM, or GFS model.
You can also select "Multiple" to toggle among the models for a specific set of parameters.
Wind speeds are color-coded with with speeds 28-37kt displayed in blue, 38-47kt in pink, and winds greater than 47kt in red.
Wind direction is indicated by the staff using a 360° compass, where 180° indicates a south wind and 360° a north wind.
Tailwind/headwind is bold when ≥30kt and crosswind is bold when ≥15kt.
The airport declination is included in tailwind/headwind/crosswind calculations for most Pacific NW and major US airports.
The solid red line indicates the highest forecast freezing level over time.
Hovering over the data points will give you more information when "tooltips" are turned on.
Clicking toward the bottom of the image will download/save the model VWP image.
In addition to the sites in the menus, most US TAF sites also should be available. Update the URL to include the site ID (https://www.weather.gov/zse/ZSEModelVWP?site=___ , where ___ is the site ID).

Calcuations of low level wind shear (LLWS) are made from the surface to the top of each near-surface (≤2,000 ft AGL) sigma level.
Table output represents the layer with the highest LLWS (speed-height). Height of the layer is in hundreds of feet AGL.
NSS (No Significant Shear) is used when LLWS <5kt. LLWS >20kt is displayed in dark red, LLWS >30kt in bold lighter red.

January 2020 Updates:
Added hover tooltips for plotted data points.
Added Wind Barb-Vertical Velocity and Temperature-Height-RH-Vertical Velocity-Wind Barb plots.
Updated declinations to grab data on-the-fly from https://www.ngdc.noaa.gov/geomag/calculators/magcalc.shtml .

October 2020 Update:
Created a horizontal model wind map page at https://www.weather.gov/zse/Wind .
