Significant Hail Parameter Added to NAM

Added the Significant Hail Parameter to the NAM-12km model.  SHIP is similar to the STP & SCP. Values above 1.0 are correlated with large hail events.  Here is more info on this product.

Tornado Passes Very Close to the Columbus, MS AFB 88D

A strong tornado passed very close to the Columbus, MS 88D tonight.  Winds were measured by the 88D up to 163 mph around 250 feet. Several other scans measured winds into the 140′s.  A debris ball and correlation co-efficient dropout indicated debris.  It’s pretty unusual to have a strong tornado so close to an 88D. But it has happened a few times in the past 30 years.

Also of note is a smaller satellite vorticie/tornado just northwest of the RDA.  It had winds to 90 mph.

 

Wright Weather Upgrading to New Facility This Saturday – Temp Outage

This Saturday -  12/22/2018  around 10AM EST our Data Center provider will be relocating our equipment into a new facility with faster and more diverse internet carriers. This new facility also has more power and satellite receiving capabilities.

This relocation will allow us to continue to expand the growing number of servers needed to process the rapid increase in meteorological data.

Around 10 AM Wright Weather will be unavailable during this transition to the new facility (about 2 miles).  We expect to have all services restored within a few hours.

Expect a disruption in the 12/22/18 12Z Model cycle output and possibly the 12/22/18 18Z Model cycles. We expect to be fully operational by the 00Z model cycle.

We appreciate your patience as we continue to grow.

 

Upgrading to GOES 16 Satellite

We will be upgrading our system from GOES 13 to GOES 16 over the next couple of days.  There may be some  interruptions in a few of the satellite products as we make this major upgrade.

The new GOES 16 satellite image will offer 60x the amount of data that the previous GOES 13 satellite provided.

Some of the improvements are noted below

  • 1km visible imagery now increased to 500 meters
  • 4km infrared Imagery increased to 2km.
  • 15 minute CONUS now increased to 5 minutes
  • 1 minute updating mesoscale sectors
  • 15 minute Full Disk scans at 6km.

Digital Storm Total Precipitation – Dual Pole Corrected

WSR-88D Digital Storm Total Precipitation has been added to all single site radars.

This product differs from the traditional Storm Total Precipiation product.

  • More color resolution
  • Uses Dual Pole data to improve ZR relationship to better estimate precipitation amounts.

This is available under the NEXRAD Radars, under the navigation menu  ”Precipitation Estimates”

Here is a link to the Houston, Texas Digital Storm Total Precipitation.
