Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 428 PM EDT Tue Jun 10 2025 Valid 00Z Wed Jun 11 2025 - 00Z Fri Jun 13 2025 ...Heavy to Excessive Rainfall likely across parts of Texas and Oklahoma over the next few days ... ...Record heat out West will begin to modify... A stationary frontal boundary draped west to east from the Southern Plains to the Southeast will be the focus for showers and thunderstorms the next several days. Anomalous moisture and instability pooling along this boundary will support daily heavy rainfall threats, particularly for parts of Texas and Oklahoma where WPC has highlighted Slight risk areas on the Excessive Rainfall Outlooks for Wednesday and Thursday and then eastward towards the Mississippi Valley by Friday. Additionally, Storm Prediction Center has most of Texas under a Marginal Risk for Wednesday and Thursday as storms will be possible with instability and outflow boundaries lingering around; hazards will be gusty winds and hail. The northern Great Basin will also see some thunderstorms ride along a frontal boundary and bring threats for severe weather and heavy rain. WPC has a Marginal Risk for Excessive Rainfall active for Wednesday across the upper Midwest and a Slight Risk (level 2/4) on Thursday as there is more confidence in a higher QPF footprint. For severe weather, the Storm Prediction Center has portions of the northern Plains and Midwest under a Marginal Risk as gusty winds and hail could be possible with thunderstorms over the nexy few days. Florida may also seem locally heavy thunderstorms and downpours as ample tropical moisture and instability bring the start to the rainy season underway. Record heat across the West should begin to subside as high pressure ridging becomes less pronounced. High temperatures out West should lower to the 80s and some low 90s opposed to the 100s seen on Monday and the weekend. Portions of southern Texas may see temperatures still reach the low 100s across the Rio Grande valley, but clouds and rainfall should hamper the extreme heat risk. Elsewhere, the central and eastern U.S. will be seasonable for early June with highs in the upper 80s and low 90s. The northern Plains and upper Midwest will be on the cooler side north of the frontal boundary with highs in the 60s.
