Time Odom City/Heading Remarks

8:55 001 COLBY, KS- Cold front had passed us overnight. Fog on the deck. It's very cold. Upper low trying to cutoff over the four corners area. Unidirectional winds are forming over the high plains. As the system deepens, the strongest jet stream winds will be kept over the intermountain region. Surface low near Great Bend, KS is messing up the convergence. I see two target areas today. One is south of the front in the Texas-Oklahoma panhandles. The other is the upslope flow in eastern Colorado provided the skies clear out. The latter seems unlikely. Thus, we've decided to head south on Rt. 25 into the Tx/Ok panhandles. Dodge City has a nine degree cap this morning.

9:12 021 Rt. 40 W. - Then Rt. 25 south.

9:32 044 RUSSELL SPRINGS - Fog has lifted cloud bases are definite.

10:06 085 LEOTI - Pit stop.

11:06 130 LAKIN - BINVOC - NE winds are light.

11:31 159 ULYSSES- Broken cumulus with blue sky above. Patchy cirrus.

Winds are northerly. Continuing south on Rt. 25

11:46 Broken clouds west, scattered clouds east. Cirrus patch SW.

12:00 190 HUGOTON - Scattered strato-cu. Cirrus patch SW. Data stop.

Carson downloaded data and plotted a map. Gene says by 2pm winds will switch around to the southeast and the action area will be in southeast Colorado. I like the Texas panhandle. We decided to wait until 2pm before making the final decision. Gene likes the Colorado area because of the veering of the winds with height whereas I like the higher CAPES in the Texas panhandle. Ate lunch. Decided to go to the Texas panhandle.

1:57 190 HUGOTON- Rt. 51 east.

2:05 200 Turned south on an unmarked road to Hooker, OK. Can now see anvils to the south. (Tornado Watch Box issued from Amarillo to Salina).
