Excessive Heat across Texas Next 3 Weeks could easily go longer
Discussion: Dry soils coupled with persistent high pressure ignite a long duration early summer heat wave across Texas. The outlook through June 15 indicates spiking heat to 106-108 on 2 occasions in Midland and 2 chances of 100 in Dallas (Fig. 1). Persistent mid-to-upper 90’s are likely San Antonio to Houston. The air mass is humid therefore extreme heat index is also likely. Heat index is consistently in the 100-108F range the next 3 weeks across Texas (Fig. 2). The anomalous heat and dry weather pattern accelerates the drought and in-turn dry soils act as a feedback mechanism to keep the hot and dry weather going possibly with higher amplitude later in June to July.
