MD 1869 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR PORTIONS OF CENTRAL/SOUTHERN ARIZONA

Mesoscale Discussion 1869
NWS Storm Prediction Center Norman OK
0701 PM CDT Thu Aug 08 2024

Areas affected…Portions of Central/Southern Arizona

Concerning…Severe potential…Watch unlikely

Valid 090001Z – 090130Z

Probability of Watch Issuance…20 percent

SUMMARY…Isolated strong to severe wind gusts remain possible into
the early evening in parts of central/southern Arizona.

DISCUSSION…A recent observed wind gust from the Tucson airport of
61 kts continues to suggest the potential for strong to severe wind
gusts exists in parts of central/southern Arizona. Outflow is also
becoming more evident on KIWA radar imagery. This outflow is
generally moving toward the Phoenix metro area. Strong to severe
wind gusts are possible as this occurs. Additional thunderstorms may
also develop as these outflow propagate into the lower deserts and
potentially interact with one another. These storms could produce
equally strong downburst winds given the very steep low-level lapse
rates.
