WeatherBrains | | Post Tag for WeatherWeather

NOAA just released their outlook today for Spring 2018 – ie the rest of the ski season 2017/18.

This outlook doesn’t look great for the vast majority of the West…

THE GOOD:

  • As far as ski country goes, NOAA is only forecasting above average precipitation in the Northeast.
  • As far as ski country goes, NOAA is only forecasting below average temperatures in Montana and the Idaho Panhandle.

THE BAD:

  • NOAA is forecasting below average precipitation in most of the West including CA, NV, UT, CO, NM, AZ, OR, WY, and southern ID.
  • NOAA is forecasting above average temperatures this Spring for the entire Northeast and most of the West including CA, NV, UT, CO, NM, AZ.

NOAA’s Mike Halpert explains the NOAA’s 2018 spring climate outlook

The Lower Mississippi faces a risk of moderate flooding this spring, while the southwest quadrant of the country is likely to see drought conditions continue or expand.  The Climate Prediction Center’s Mike Halpert provides more details of NOAA’s 2018 spring climate outlook.

Minor to moderate flood risk throughout Mississippi watershed

Spring 2018 flood risk in the contiguous United States. Areas vulnerable to minor flooding are light blue;  moderate flooding, medium blue. These maps reflect places where the “background” climate conditions—such as a wet winter and saturated soils—create an enhanced risk of flooding throughout the season. Flash flooding can still occur anywhere in response to extreme weather.  NOAA Climate.gov map, based on data from the Climate Prediction Center.

Highest chances for warm spring: Hawaii, Southwest, Gulf Coast

Areas of the United States where the average temperature for April-June 2018 is favored to be in the upper (reddish colors) or lower (blue colors) third of the 1981-2010 seasonal temperature record. Within a given area, the intensity of the colors indicates higher or lower chances for a warm or a cool outcome, not bigger or smaller anomalies. For example, both Texas and Tennessee face better than even chances of experiencing well above average spring temperatures,  but the chances are higher in Texas (60-70%) than in Tennessee (40-50%).  NOAA Climate.gov map, based on data from NOAA CPC.

 

Highest chances of a wet spring: Great Lakes, central Alaska, Hawaii

Places where the 2018 forecast favors well above normal (green) or well below normal (brown) spring precipitation.  Within a given area, the intensity of the colors indicates higher or lower probability for a wet or dry outcome, not how wet or dry the season is predicted to be. For example, both Nevada and southern Idaho are favored to experience a much drier than normal spring, but the odds of such a dry spring are higher in Nevada (40-50% chance) than Idaho (33-40% chance).

Largest drought footprint likely to be in Southwest
