  1. This Year (2014) So Far/ A Look Ahead John Lewis, Senior Forecaster National Weather Service Little Rock, Arkansas

  2. The Year 2014 It has been cool and somewhat dry so far in 2014 (through April). The window is closing on when we typically get substantial rain in Arkansas (in the spring). Precipitation usually scatters out in the summer. We appear to be transitioning from neutral conditions in the equatorial Pacific to El Niño (warmer than normal water).

  3. Precipitation 2014 (Through April)

  4. Precipitation 2014 (Through April)

  5. Precipitation 2014 (Through April)

  6. Already Relief Early May, 2014 One to three inches of rain fell in western Arkansas in the twenty four hour period ending at 700 am CDT on May 9th. Local amounts exceeded six inches.

  7. Temperatures 2014 (Through April)

  8. Arkansas Drought April 29, 2013

  9. U.S. Drought April 29, 2014

  10. Severe Weather 2014 It was a slow start to the severe weather season, with only one tornado through mid-April. Five more tornadoes were spawned on the 27th.

  11. Severe Weather 2014 One of the tornadoes tracked 41 miles through Mayflower and Vilonia (both in Faulkner County), and was rated EF4 (166-200 mph winds).  

  12. Severe Weather 2014 Rotation was intense at 738 pm CDT on the 27th. At this time, the tornado was between Mayflower and Vilonia (both in Faulkner County).

  13. Severe Weather 2014 There was a debris ball detected. This indicated a tornado was present and causing damage.

  14. ENSO Through the End of 2014

  15. The Last Few Years Blue – La Niña Red - El Niño Early 2008/2011: Very active with a lot of severe weather (including tornadoes). 2009: Record wet year. Summers 2010-2012: Top 15 warmest/drought.

  16. The Transition Neutral to El Niño

  17. The Forecast Long Term Precipitation

  18. The Forecast Long Term Temperatures

  19. Summers 2010-2013

  20. The Tropics Given El Niño conditions, shear will increase over the Atlantic Ocean, and this will make the tropics less active (fewer storms).

  21. Official Outlook Precipitation (Summer, 2014)

  22. Official Outlook Temperatures (Summer, 2014)

  23. U.S. Drought Outlook Through July, 2014

  24. Putting Words to It We are keeping an eye on the western half of Arkansas for possible drought development. If a drought does unfold, the transition to El Niño may keep it short-term (since most transitions have resulted in above normal precipitation locally). Look for more warmer than normal days than earlier in 2014, but not a summer with relentless heat and little rain.
