Weather Alerts For Hatton, AR
Severe Storm Risk
-There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON/EVENING FROM ARKANSAS TO NORTHWEST GEORGIA SUMMARY Large hail, damaging winds and a couple of tornadoes are possible this afternoon/evening from the Mid-South into northwest Georgia. AR to north GA this afternoon/evening A weak mid-upper speed max is cresting the larger-scale ridge and will move from AR to the TN Valley this afternoon/evening. Associated/ongoing convection across AR will likely persist through the afternoon with some tendency for upscale growth, while spreading eastward along the northern gradient of boundary-layer dewpoints in the low-mid 60s. Surface heating in cloud breaks, beneath the eastern extent of 7-8 C/km midlevel lapse rates, will contribute to moderate buoyancy (MLCAPE of 1000-1500 J/kg) along this corridor with minimal convective inhibition. Deep-layer vertical shear will be sufficient for a somewhat organized/bowing storm cluster to evolve from the ongoing AR storms as they spread across the TN Valley this afternoon, potentially reaching northwest GA by late evening. The initial storms in the cluster will pose a threat for large hail (1-2"diameter), with some increase in the threat for wind damage from northern MS across northern AL/northwest GA. More discrete storms will be possible immediately south of the MCS path this afternoon/evening as a maritime tropical air mass (68-72 F dewpoints) spreads inland. Wind profiles will support supercells capable of producing large hail (some could exceed 2 inches in diameter). A modest increase in low-level shear this afternoon, combined with rich low-level moisture and the possibility of lingering convective outflow from the ongoing storms in AR will also support the potential for a couple of tornadoes. Isolated thunderstorm development may also occur farther southwest along the marine warm front into southeast TX, where there is a conditional threat for large hail. Southern AZ this afternoon/evening High-based, low-topped convection is expected in the band of ascent immediately north-northeast of the closed low near northern Baja. Low-level moisture will be somewhat limited, but steep low-midlevel lapse rates and substantial south-southeasterly deep-layer shear will support a few storms/clusters capable of marginally severe hail and gusts approaching 60 mph.
Pollen Alert
-Pollen Index: 10.7 Pollen Level: high Predominant Pollen: Elm and Maple The quantity of pollen grains in the air for Monday will be increasing and extend further into the very high range. This results in part from rising temperatures.
